Description

Organic rectifier
Technical Field
Rectifier technical field the present invention relates to a rectifier comprising at least two organic diodes or organic field effect transistors, for example in the form of a Radio Frequency Identification (RFID) transponder and a flexible multilayer film body.
Background
RFID transponders are increasingly used for goods, articles or security products with electronically readable information. Thus, transponders may be used in security assemblies, for example in conjunction with electronic bar codes for consumer goods, baggage tags to identify baggage, or passport sleeves for storing authentication information.
RFID transponders generally comprise two elements: an antenna and a silicon chip. The RF carrier signal transmitted from the base station is connected to the antenna resonance circuit of the RFID transponder. The silicon chip modulates additional information on the signal fed back to the base station. In this case, the RFID transponder does not normally get a separate power source. The silicon chip is powered by a rectifier that converts the RF carrier signal connected to the antenna resonant circuit to a DC voltage. Therefore, rectifiers are also used as power supplies for silicon chips.
In order to reduce the production costs of RFID transponders, it has been proposed to use organic integrated circuits in RFID transponders, the main component of which is an organic field effect transistor. Thus, for example, WO99/30432 proposes the use in an RFID transponder of an integrated circuit consisting essentially of organic material, which integrated circuit provides the function of an ID code generator. The ID code generator is connected to the supply voltage via two rectifier diodes connected to the antenna resonant circuit. A rectifying diode with a smoothing capacitor connected to the output of the rectifying diode comprises two field effect transistors that are exclusively interconnected.
Although the use of the above-described specially interconnected field effect transistors allows to realize the rectifier diodes as organic components, the frequencies that can be captured in the organic field effect transistor diodes are very limited if the field effect transistors are connected in the above-described manner to function as rectifier diodes, since the switching of s is usually much slower than the RF carrier frequency.
Typical frequency ranges used in RFID transponders are, for example, 125 to 135kHz, 13 to 14MHz, 6 to 8MHz, 20 to 40MHz, 860 to 950MHz or 1.7 to 2.5 GHz. However, organic circuits typically have lower charge carrier mobility than silicon, and organic circuits are much slower than all silicon-based circuits because organic field effect transistors are based on charge carrier accumulation rather than charge carrier inversion. This results in lower switching speeds and different switching operations (e.g., insufficient ac voltage) compared to silicon transistors. If organic field effect transistors are connected to construct a rectifier as described in WO99/30342, the rectifier implemented will switch much slower (less than 100 KHz) than the transmission frequency of the carrier signal emanating from the base station.
WO02/21612 also proposes the construction of an organic rectifier in which the conventional pn semiconductor diode is supplemented or replaced by an organic conductive material in at least one conductive layer doped with pn. Furthermore, it is proposed to replace at least one layer with an organic layer in conventional metal semiconductor diodes (schottky diodes). The switching frequency of a switching rectifier can be set by selecting the area of the capacitor region of the rectifier. Further, a smoothing capacitor is connected to the output of the rectifier composed of the organic component described above, so that the smoothing capacitor is pulsed to the output of the rectifier and the smoothing capacitor smoothes the reached DC voltage in parallel with the load resistance. It becomes.
However, the organic rectifiers described above are also not very effective at frequencies above 1 MHz. This is due to the low mobility of currently available organic semiconductors and the possibility of use in the organic rectifiers described above. Due to the low charge carrier mobility in organic semiconductors, the space charge region leading to the commutation effect is no longer built up fast enough at high frequencies. As a result, the efficiency of the rectifier is reduced, making it more difficult to provide a dc voltage to the load of the output stage.
Disclosure of Invention
The present invention therefore aims to improve the voltage supply to the load at the output stage using an organic rectifier.
This object is achieved by a rectifier for converting an alternating voltage between two input terminals of the rectifier into a direct voltage, comprising at least two organic diodes and/or organic field effect transistors, each organic diode being converted into an organic diode. The field effect transistor can be constructed in such a way that the at least one electrical functional layer of the semiconducting organic material and the charging or charge reversal capacitor can be charged via different current paths. Two or more charging or reverse charging capacitors connected to an organic diode or an organic field effect transistor. The object is also achieved by an electronic device in the form of a flexible multilayer film body comprising a power supply and a rectifier configured in the above-described manner, which rectifier is connected to the power supply.
In this case, the invention is based on the concept of compensating for the low charge carrier mobility of an organic semiconductor by the interconnection of two or more charge or oppositely charged capacitors charged via different current paths of a rectifier.
As described above, the interconnection of the capacitor and the organic component constituting the organic rectifier greatly increases the rectification coefficient GRS =. Experimental results show that, for example, at a frequency of 13.56Mhz, only about 5% of the amplitude of the connected ac voltage is converted from output to dc voltage, which corresponds to a rectification factor of GRV = =0.05, while the dc voltage is at the output stage. It becomes very difficult to supply the load. Thus, many experts now believe that it is not possible to rectify the combined high frequency signal with organic components. The use of organic rectifiers in RFID transponders has been rejected due to the low carrier mobility of the currently known organic semiconductors. The invention therefore proposes an improvement and makes it possible to supply the required DC voltage to an organic rectifier of a load connected to the output terminals even at high frequencies by means of the interconnection of a charged or reverse-charged capacitor with the above-mentioned organic components. In this case, possible loads include organic logic circuits, display components and conventional electronic devices.
In this case, the rectifier according to the present invention includes a multilayer structure composed of two, three or more layers, at least one of which is an active layer composed of an organic semiconductor material as a component. In this case, the organic diode realized in a multilayer structure includes a metal semiconductor junction or a pn junction together with the organic semiconductor, in which case the metal may be replaced by an organic conductor. In this case, the order of the respective functional layers may be arranged vertically and laterally. It is also contemplated to introduce additional intermediate layers to supplement the actual functional layers to improve electrical properties (e.g., injection of carriers).
An organic field effect transistor in which a gate electrode is connected to a source electrode or a drain electrode can also be used as an organic diode in a rectifier.
Advantageous developments of the invention are mentioned in the dependent claims.
According to a first embodiment of the invention, the first charging capacitor and the first organic diode are arranged in the first conductor branch and the second charging capacitor and the second organic diode are arranged in the second conductor. The first and second wires are connected in parallel to the input of the rectifier, and the first and second organic diodes have one anode electrode and the other cathode electrode back to back. Back) to cause alignment.
According to another embodiment of the present invention, the first and second organic diodes may be connected to an anode electrode of one of the organic diodes and a cathode on the other cathode in a back-to-back alignment to form a reverse charging capacitor. Is connected to a first input terminal of the rectifier. The first organic diode is connected to the second input terminal of the rectifier. The second organic diode is connected to the second input terminal of the rectifier via a charging capacitor. According to the alignment, the cathode of the first organic diode and the anode of the second organic diode are connected to the first input terminal through the reverse charging capacitor, and the anode of the first organic diode and the cathode of the second organic diode, which are charging electrodes, may be connected to each other, and the anode of the first organic diode may be connected to the second input terminal. However, the anode electrode of the first organic diode and the cathode electrode of the second organic diode are also connected to the first input terminal through the reverse charging capacitor, so that the cathode electrode of the first organic diode and the anode electrode of the second organic diode are the charging capacitors. It may be connected to each other, and the cathode of the first organic diode may be connected to the second input terminal.
An organic rectifier constructed in this way has the advantage that the supply voltage available on the output side can be increased even with low consumption. The organic rectifier can be manufactured cost-effectively, for example by a roll-to-roll process.
By constructing a rectifier with two or more stages connected to each other, the supply voltage available at the output side can be further increased. Each stage of the rectifier comprises two charging or reverse charging capacitors and two organic diodes or organic field effect transistors connected in such a way that the charging or reverse charging capacitors are charged through different current paths, each stage in this case comprising two input terminals and two connection terminals for connection to the next input terminal.
In this case, the rectifier may comprise stages of the same type connected in two or more cascades.
In a particularly advantageous embodiment of the stage designed for the cascade connection described above, the cathode of the first organic diode and the anode of the second organic diode are connected to the first connection terminal of the first stage and to the first stage via a reverse charging capacitor. Which is connected to a first input terminal of the platform. The anode electrode of the first organic diode and the cathode electrode of the second organic diode are connected through a charging capacitor. An anode of the first organic diode is connected to an input terminal of the stage, and a cathode of the second organic diode is connected to a second connection terminal of the stage. The stage configured in this manner will be referred to as a "first stage" hereinafter.
The anode of the first organic diode and the cathode of the second organic diode may also be connected to the first connection terminal of the platform and the first input terminal of the platform by a reverse charging capacitor. The cathode of the first organic diode and the anode of the second organic diode are connected to each other through a charging capacitor. A cathode electrode of the first organic diode is connected to the second input terminal of the stage, and an anode electrode of the second organic diode is connected to the second connection terminal of the stage. The stage constructed in this way is hereinafter referred to as "second stage".
In the cascade connection of the first and second stages, the first and second input terminals of the first stage form the first and second input terminals of the rectifier, respectively. Unless each stage constitutes the last stage of the rectifier, the connection terminal of each stage will be connected to the input terminal of the next stage. The output of the rectifier is formed by the second input terminal of the front end and the second connection terminal of the rear end.
The first and second stages may also be connected to each other in a rectifier. In the rectifier constructed in this manner, the first and second input terminals of the first and second stages are connected to each other to form the input terminals of the rectifier. In this case, any number of first and second stages are connected in series to the connection terminals of each preceding first and second stage, respectively, in this manner. The output of the rectifier is formed by the second connection terminal of the last stage and the second connection terminal of the last second stage.
An advantage of the above arrangement of two different types of stages is that the DC current available at the load of the output stage at the same supply voltage can be increased.
As the organic diode, the rectification coefficient can be further improved by using an organic component including an intermediate layer that reduces the parasitic capacitance of the organic diode. The efficiency of the charging/reverse charging process in the charging/reverse charging capacitor is improved due to the reduced parasitic capacitance of the organic diode, and thus the efficiency of the rectifier is also improved.
According to a further embodiment of the invention, the first and/or second input terminal of the rectifier is connected to the reverse charging capacitor via one or more first field effect transistors. The reverse charging capacitor is connected to the charging capacitor through one or more second field effect transistors. One or more of the first and second field effect transistors are driven by a logic circuit. In this case, the logic circuit drives the first field effect transistor in such a manner that an alternating voltage is applied to the reverse charging capacitor.
The rectifier according to the invention has particular advantages when used in an electronic device having a resonant circuit comprising an antenna and a capacitor as a voltage source. By connecting the antenna resonant circuit to the rectifier according to the invention, a DC voltage source for the output stage electronic component can be produced particularly economically, which can provide a sufficient supply voltage and can be realized in the form of a flexible body. . It is also of particular advantage if the organic integrated circuit is used as an electronic component in an output stage. Due to the special properties of organic integrated circuits (e.g. very low current requirements), the above-described circuit is particularly suitable for the characteristics of the rectifier according to the invention. This type of electronic device can also be economically manufactured using the same standard manufacturing techniques for mass production applications and disposable products.
In addition to using the aforementioned resonant circuit as a voltage source, an oscillator such as a ring oscillator or corresponding two or more field effect transistors are provided in the voltage source to drive the charging and/or reverse charging capacitors. A voltage may also be applied.

Detailed Description
The rectifiers shown in fig. 1 to 5 each comprise a flexible multilayer film body comprising one or more electrical functional layers. The electrically functional layers of the film body comprise an organic electrically conductive layer and an organic inversion layer and/or an organic insulating layer which are arranged on top of one another in an at least partially structured form. Along the electrically functional layer, the multilayer film body optionally also comprises one or more carrier layers, protective layers, decorative layers, adhesion-promoting layers or adhesive layers. The electrically conductive functional layer preferably comprises an electrically conductive metallization structure, preferably made of gold or silver. However, it is also possible to make provision for the functional layer to be formed from a conductive material, which is an inorganic material, such as indium tin oxide, or a conductive polymer, such as polyaniline or polypyrrole. Functional layers associated with organic semiconductors include, for example, spin-coated, blade-coated adhesive polymers, such as polythiophene, polythiophene vinylene or polyfluorene derivatives. Or by printing from a solution. When vapor-deposited by vacuum techniques, so-called "particles", i.e. oligomers such as hexathiophene or pentacene, are also suitable as organic semiconductor layers. These organic layers are preferably applied in a partially structured manner or in a patterned manner by printing methods (engraving, screen printing, pad printing). To this end, in this case, the electrically functional layer of each film body is configured to realize the circuit shown in fig. 1 to 5.
In each case, the circuits described with reference to fig. 1 to 5 comprise two or more charging or reverse-charging capacitors and two or more organic diodes.
Organic diodes are realized by metal-semiconductor junctions or pn junctions between n-conducting and p-conducting semiconductors in a multilayer film body. In this case, the order of the respective functional layers may be arranged vertically and laterally. Additional intermediate layers that supplement the functional layers can also be introduced to improve electrical properties (e.g., to infuse nutrient carriers). The organic diode is thus realized, for example, by three successive layers, wherein the first layer is a conductive electrode layer forming the cathode, the second layer is a layer composed of an organic semiconductor material, and the third layer is the anode. And forming a conductive electrode layer. In this case, the organic semiconductor layer has a layer thickness of, for example, 60 to 2000 nm. The conductive layer may comprise one of the above-mentioned materials, i.e. it may comprise a metallic or organic conductive material which may be applied by a printing process.
The organic diode can also be realized by a four-layer structure consisting of two electrode layers and two organic semiconductor layers, wherein the two electrode layers and the two organic semiconductor layers have an n-conductive property therebetween and the other has a p-conductive property.
Reference is made hereinafter to the content of WO02/21612A1 regarding the construction of organic diodes.
The organic diode may also be configured as an organic field effect transistor in which the gate electrode is connected to the drain electrode.
A charged or reverse-charged capacitor implemented in a multilayer film body is formed by two conductive layers and an insulating layer between them. The conductive layer may consist of one of the materials mentioned above, for example a metal layer or an organic conductive layer applied by a printing method. In this case, the capacitance of the charging or reverse charging capacitor ranges from 1pF to 2 nF.
Fig. 1 shows a rectifier 1 comprising two organic diodes OD1, OD2 and two charging capacitors C1, C2. The rectifier 1 has an input E1 with input terminals E11, E12 and an output a 1. The input terminal E11 is connected to the cathode of the organic diode OD1 and the anode of the organic diode OD 2. The anode of the organic diode OD1 is connected to the input terminal E12 through the charging capacitor C1, and the cathode of the organic diode OD2 is connected to the input terminal E12 through the charging capacitor C2. The output voltage is tapped between the cathode of the organic diode OD2 and the anode of the organic diode OD 1.
The AC voltage input to the input terminal E1 is rectified by the organic diode OD1 at a negative voltage applied to the charging capacitor C1, and rectified by the organic diode OD2 to form a positive voltage. Thus, the DC voltage output at output terminal a1 corresponds to the sum of the voltage magnitudes across capacitors C1 and C2.
Fig. 2 shows a rectifier 2 with a reverse charging capacitor C1, a charging capacitor C2 and two organic diodes OD1, OD 2. The rectifier 2 has an input E2 with two input terminals E21 and E22, an output a2 and two connection terminals B21 and B22. One end of the reverse charging capacitor C1 is connected to the input terminal E21, and the other end is connected to the connection terminal B21, the cathode of the organic diode OD1, and the anode of the organic diode OD 2. One end of the charging capacitor C2 is connected to the anode and the input terminal E22 of the organic diode OD1, and the other end is connected to the cathode and the connection terminal B22 of the organic diode OD 2. The output voltage is tapped off by a charging capacitor C2. The input ac voltage applied to the input terminal E2 is rectified by the organic diode OD1 to form a voltage across the reverse charging capacitor C1. During the positive half-cycle of the input AC voltage, the positive charge located in the reverse charging capacitor C1 may be transferred to the charging capacitor C2 through the organic diode OD 2. Thus, the increased amount of voltage is across the charge capacitor C2 and can be drawn through the output a 2.
Fig. 3 shows a rectifier 3 with a reverse charging capacitor C1, two organic diodes OD1, OD2 and a charging capacitor C2. The rectifier 3 has an input E3 with two input terminals E31 and E32, one output A3 and two connection terminals B31 and B32. One end of the reverse charging capacitor C1 is connected to the input terminal E31, and the other end is connected to the anode of the organic diode OD1, the cathode of the organic diode OD2, and the connection terminal B31. One end of the charging capacitor C2 is connected to the cathode and the input terminal E32 of the organic diode OD1, and the other end is connected to the anode and the connection terminal B32 of the organic diode OD 2. The output voltage is tapped off by a charging capacitor C2. In the case of the rectifier 3, the negative charge at the reverse charging capacitor C1 during the negative half-cycle of the input AC voltage is transferred by the organic diode OD2, which organic diode OD2 is directed to the charging capacitor C2, in contrast to the rectifier 2. Thus, the increasing negative voltage is across the charge capacitor C2 and tapped through the output A3.
The rectifiers shown in fig. 2 and 3 may be connected in a cascade arrangement, respectively, forming a multi-level organic or printable rectifier.
Fig. 4 exemplarily shows the rectifier described above. Fig. 4 shows a rectifier 4 composed of two or more stages, two stages S41 and S42 shown in fig. 4. Each stage S41, S42 is constructed analogously to the rectifier 2 according to fig. 2. Thus, stage S41 has an input with two input terminals E41, E42, an output a41 and two connection terminals B41, B42. The stage S42 has two input terminals E43 and E44, one output a42 and two connection terminals B43 and B44. The input terminal and the connection terminal of each of the stages S41 and S42 are connected to the reverse charging capacitor, the charging capacitor and the two organic diodes shown in fig. 1.
The input terminals E41, E42 of the first stage of the rectifier 4 form the input of the rectifier 4, which is designated by E4 in fig. 4. The input terminals of the next stage are connected to one terminal of the rectifier 4, respectively. Therefore, the DC voltage at the output side is generated by the sum of the output voltages output from the respective stages, so that the voltage at the output a4 of the rectifier 4 is further increased.
The rectifier 4 may also be configured by a cascade arrangement configured as individual stages of the rectifier 3 according to fig. 3.
Fig. 5 shows a rectifier 6 consisting of different stages in different configurations. On the other hand, the rectifier 6 has two or more stages, each stage being configured as a rectifier 2 according to fig. 2.5 of the stages have input terminals E61 and E62 and input terminals E63 and E64, respectively, connection terminals B61 and B62 and connection terminals B63 and B64 and outputs a61 and a 62. Two stages S61 and S62 are shown. The stages are connected to each other in a cascade arrangement such that the input terminal of the next stage is connected to the connection terminal of the previous stage, as already described with reference to fig. 4.
The rectifier 6 also has two or more stages, which are configured as a rectifier 3 according to fig. 3.5 of the stages have input terminals E61 and E62 and input terminals E65 and E66, respectively, connection terminals B65 and B66 and connection terminals B67 and B68 and outputs a63 and a 64. Two stages S63 and S64 are shown. The stages are also depicted in fig. 4 and are connected to each other in a cascade manner such that the input terminal of the next stage is connected to the connection terminal of the previous stage. The inputs of the stages S61, S63 are connected to the input E6 of the rectifier 6, respectively, the positive output voltage of the outputs of the stages S61, S62 being the negative voltage of the outputs of the stages S63, S64. The voltage applied to the rectifier 6 and thus the output voltage at the output a6 of the rectifier 6 increases.
Fig. 6 shows an electronic device 5 with a power supply 51, a rectifier 52 and an electronic circuit 53 connected to the rectifier 52. The electronic device 5 is an RFID transponder. As already described with respect to fig. 1-5, the electronic device 5 comprises a multilayer flexible film body having two or more electrically functional layers. In this case, the power supply 51 is formed by an antenna resonance circuit composed of an antenna and a tuning capacitor. The rectifier 52 is formed by a rectifier configured as one of the rectifiers 1, 2, 3, 4 or 6 according to fig. 1 to 5.
The electronic circuit 53 is an ID code generator consisting of one or more active or passive organic components, preferably organic field effect transistors.
However, the electronic circuit 53 may also provide a different function or be replaced by an output unit formed, for example, by an organic LED or LCD.
Fig. 7 shows an electronic device 7 for supplying power to an organic or printable logic circuit. The electronic device 7 comprises a voltage source 71, a logic circuit 72, a plurality OF organic field effect transistors OF1, OF2, OF3, OF4, two reverse charging capacitors CS1, CS2 and a charging capacitor CO. There are. The two reverse charging capacitors CS1 and CS2 each have the capacitance of the charging capacitor CO and may be replaced by a capacitor having a capacitance twice or more than this capacitance. In this case, the logic circuit receives a voltage from the output voltage of output a7 of the electronic device.
The voltage source 71 provides any AC voltage with or without a DC voltage component. The voltage source 71 may be formed by, for example, an antenna resonance circuit according to fig. 6 and/or a battery, such as a printed battery or an accumulator. The logic circuit 72 includes one or more organic field effect transistors connected to each other. The logic circuit 72 controls a switch matrix including organic field effect transistors OF1 to OF 4. By properly configuring and driving the switch matrix, a dc voltage can be generated at the output of the switch matrix through the charging and reverse charging processes. The logic circuit 72 drives the organic field-effect transistors OF1 to OF4 in the following manner: such that field effect transistors OF1 and OF2 are on and field effect transistors OF3 and OF4 are off, e.g., positive half cycles. During the next positive half cycle, the organic field effect transistors OF3 and OF4 are on, while the organic field effect transistors OF1 and OF2 are off.
It is also possible to provide more organic field effect transistors in the switch matrix, for example to take advantage of the negative half-cycles of the voltage source 71. This also increases the dc voltage at the input side of the switch matrix.
Fig. 8 shows an electronic device with a voltage source 81, an oscillator 82 and a rectifier 83. The rectifier 83 has an input and an output 8 with two input terminals a81 and a 82. The rectifier 83 is configured as one of the rectifiers 1, 2, 3, 4 and 6 according to fig. 1 to 5.
The voltage source 81 is for example a DC voltage source, for example a battery. The voltage source 81 may also be a rectifier constructed according to fig. 1 to 5 and connected to an AC voltage source, for example an antenna resonant circuit.
Oscillator 82 is a printable ring oscillator that converts the input voltage to have an AC voltage, preferably at a frequency of less than 1 MHz. The rectifier 83 is a rectifier configured as one of the rectifiers according to fig. 1 to 5. By this arrangement the voltage is effectively rectified to a DC voltage at the output 8.
In this way, it is also possible to combine the rectifier according to fig. 1 to 5 with the rectifier according to fig. 7, i.e. the rectifier according to fig. 1 to 5 forms the voltage source 71 according to fig. 7 together with the alternating voltage source. With this type of arrangement, impedance matching of the electronic circuit provided by the rectifier can be obtained, for example.
