Description of the invention: [Technical field to which the invention belongs] The present invention is a power-on reset circuit for generating a power-on reset pulse signal. [Prior technology] The mission function of the integrated circuit may be performed erraticly without the help of a power-on reset circuit. From the initial voltage rise of the main voltage supply source until the main voltage supply source has fully risen to supply power to an integrated circuit or a part of the integrated circuit as expected, the power-on reset circuit immediately provides a delay ... In other words, the output of the power-on reset circuit is a uniform input of a circuit connected to the mission function of the execution circuit. The U.S. Patent No. 5,936,444 has a thunderbolt ga +, 1 reset circuit that relies on a transistor with a command voltage. However, ′ has the step of zero-interval plus CM0S manufacturing process, thus substantially increasing the cost. "The body ~ the production" because there is no need to madly rely on the zero-intermediate voltage transistor to generate work power to open the reset circuit. [Summary of the invention] The present invention provides a method for generating a lightning force geoelectric The knife-on reset letter method, the power-on reset is performed on the right side of the gangway and the corpse, the left tiger has a hading part, a blood trailing part (Pm), and is one of the present invention. Implementation mode +, ,,, and store, from the electric power station, a power supply, a ground terminal, an output voltage and power out 轮 α, a power out node ... starting circuit, and a--". The starting circuit is suitable for initial determination of the output voltage of the immediate point ^ 1237943 Eight of any node voltage 'and is suitable for generating the leading part before the power-on reset signal. The example of the knife 1 starting circuit is a voltage detector. The signal source circuit is suitable for the input of the signal source circuit—the input voltage exceeds the signal source circuit—the disconnection point—for example, is an electrical detector. All the threshold voltages of all the transistors of the circuit generating the power-on reset signal have zero threshold voltages by ion implantation. In some cases, the 'starting circuit' includes a voltage pick-up, a transistor, and a capacitor connected to the voltage supply and ground. Voltage detection of starting circuit, U; r, connect to $ voltage supply source and ground terminal. The voltage detection circuit of the starter circuit has -input and output connected to the capacitor. The transistor system is connected to the terminals and the output of the voltage controller, and for example to isolate the starting circuit from the power-on reset signal before the signal source circuit generates a trailing portion of the power-on reset signal. This isolation is useful after the leading portion of the start-up circuit has generated the power-on reset signal and when the signal source is generating the trailing portion of the power-on reset signal. In this case, the starting circuit and the signal source generate an inconsistent signal (ConnHcting & ⑽1) used by the power supply reset reset signal. In the implementation of Λ, the starting circuit includes a voltage generator, a transistor and a capacitor. By switching the voltage supply source to one of the gates of the first transistor, the output of the voltage controller of the starting circuit generates electricity to turn on the power. Leading part 0 before setting the rhyme. In another example, the starting circuit includes a voltage detector and a capacitor. In response to the voltage supply source—the continuous voltage rises, the heart voltage exceeds the voltage generator—the disconnection point. The tester is connected to the grounding terminal. The gate of one of the first transistors, and the first circuit breaker is isolated from the start circuit and the power-on reset signal. 1237943 In another embodiment, for example, in the signal source circuit When the input input voltage exceeds the disconnect point voltage of the signal source circuit, the voltage detector of the signal source circuit generates a trailing portion of the power-on reset signal. ^ Certain embodiments include a feedback crystal. Feedback power The crystal has a first current-carrying terminal connected to the voltage supply source, a second current-carrying terminal of the voltage detector connected to the signal source circuit, and an output connected to the signal source circuit: ―, gate After the signal source circuit generates the trailing portion of the power-on reset signal, the feedback circuit isolates the voltage supply source and the signal source circuit, thereby saving power after both leading and trailing portions are generated before the power-on reset signal has been generated. Therefore, In order to generate the trailing portion of the power-on reset signal, the voltage supply source is isolated from the signal source circuit that generates the trailing portion of the power-on reset signal. In various embodiments, a voltage rise of one of the voltage supply sources causes a Or multiple different responses. Under this kind of response, the voltage at the input of the signal source circuit is set to be lower than the disconnection point of the signal source circuit, for example, by connecting the input of the signal source circuit to the ground terminal. Voltage. In another response, the signal source circuit generates a signal that matches the leading part of the power-on reset signal—this consistency is related before the signal source circuit generates the trailing part of the power-on reset signal. Before the voltage supply continues to rise, the signal source circuit has not yet generated power to reset the trailing part of number k. Therefore Before the voltage supply continues to rise: before 'If the signal source circuit generates a signal that is equal to the leading part before the power-on reset signal, the output of the signal source circuit does not need to be isolated from the power-on reset signal. In the embodiment, after the voltage of the voltage supply source rises, the continuous voltage rise of the voltage supply source causes a response, for example, by consuming the input of the inverter to the voltage supply source, the One input one voltage is raised to the voltage at the disconnection point of the signal source circuit. 1237943 In one embodiment of the present invention, a power on reset is provided, and the method of generating ~ power on reset signal It has — ϋ points. Mm wide rules — part and a trailing part are in response to a voltage rise of a voltage supply source, the voltage of this node is initialized, and the power is turned on and reset. Even if it ’s partial, there is a guide to setting it up. Part of the system is to determine the output voltage of the output nodes. -Signal source: The input voltage of the circuit is set by having a non-intermediate value: at least one first transistor which is adjusted by the ion implantation method. In response to the continuous rise of one of the voltage supply sources, the input voltage of the signal source circuit is increased to exceed that of the signal source circuit. The trailing part of the power-on reset signal is generated from the signal source. In the embodiment, the steps of generating the leading part of the power-on reset signal include multiple steps. — The inverting 11 output is a voltage connected to the voltage supply source, so that the output voltage of the inverter is output to the voltage of the power supply. The voltage supply source is connected via the inverter S to the gate connected to the ground terminal, and the crystal is turned on. —Second Phase Inverter—The input is connected to the ground terminal via a transistor connected to the ground terminal so that the voltage at the input of the second inverter is lower than the disconnection point of the inverter. In her example, the input voltage of the hbl source is via at least a second transistor having a non-zero threshold voltage adjusted by the ion implantation method. The first and second transistor systems are connected to different voltages, such as a voltage supply source and a ground terminal. Circuit elements such as transistors and resistors connect the first and second transistors to different voltages, thereby allowing two different voltages to be coupled to the input voltage of the signal source at the same time. In the Fang and Bei examples, the k source generates a signal that matches the leading part of the power-on reset signal. Before the voltage source continues to rise, the signal source has not yet generated a trailing portion of the power-on reset signal. Therefore, before the success of the voltage supply source rises, if the signal source generates a #f which is in accordance with the f part before the power-on reset signal, the output of the signal source does not need to be isolated from the power-on reset signal. 1237943 Another embodiment of the power-on reset after cutting is a benefit in that the power consumption of the circuit that generates the power-on reset signal is negligible.

The starting circuit is connected as follows. The transistor π has one Gate connected to node 112, and two current-carrying terminals connected to ground terminal 1 () 8. Transistors 114, 122, and 120 each have one current-carrying node connected to node 112 and another to voltage supply source 105. A current-carrying terminal. The gate of transistor m and the gate of transistor 14 are connected to node 2. The gate of transistor 1 is connected to node 18. Inverter 116 has a j% input And an output connected to node 118. The inverter is used as a voltage detector which generates a leading part of the power-on reset signal in response to a voltage rise from one of the voltage supply sources. The transistor 24 has a connection To the connection: the current-carrying terminal of terminal 丨 08, the other current-carrying terminal connected to node 126, and one connected to the gate of node 118. Inverter 1 52 has an input connected to node 1 50 and Connect to one of the outputs of nodes 1 to 26. Inverted 1 28 has one input connected to node 126 and one output generating power on reset signal 1 30. The output of inverter 128 is connected to the output point of the power on reset circuit. Because the voltage of node 12 6 determines the power The value of the reset signal is on, so node 126 is the node that determines the output voltage of the 10 1237943 rounds of the output node. Lei Λ, set " 2 " ... No. 130 is the tail slave for generating power to reset Input of one of the signal source circuits. The signal source circuit is connected as follows. Transistor 132 has a gate to turn on the reset signal 130, which is connected to the current-carrying terminal of ground terminal 108: The -2 solid is connected to the transistor-34-the current-carrying terminal of the current-carrying terminal 2. The electrical conductor m, 38 has a connection to a voltage supply source, and the 5 is connected to the node 40 and the transistor. One of the current carrying terminals between the current carrying terminals of 132 ~ terminals. The transistor 42 has a gate connected to the node-, a current carrying terminal connected to the node 14G, and another one which is connected to the power source of the battery. Carrying current terminal. Turn on as power The trailing part of the signal is 1-voltage detection. The transistor 144 and 146 inverters have an input connected to node 140 and an output connected to node 150. Among them, one of the transistor currents The terminal is connected to the ground terminal 108. One of the current-carrying terminals of the transistor 146 is connected to one of the current-carrying terminals of the transistor 148. The transistor 148 has a gate connected to the node, point 126, and one connection. To the transistor ⑽-the current-carrying terminal of the current-carrying terminal, and another current-carrying terminal connected to the voltage supply source 05. ^ Figure 2 shows a processing flow of the leading and trailing parts of generating a power start setting signal. At 205, the voltage of the voltage supply source 105 rises from the ground voltage. This voltage rise causes the leading part of the power-on reset signal 13 to be generated, as shown below. At 210, one of the capacitors of the starting circuit before the power-on reset signal is generated is charged from the voltage supply source 05. In this example 1, the capacitor is a transistor connected to a capacitor, such as a transistor. The voltage of the charging capacitor determines the voltage of node 112, which also determines the inverter ιΐ6 = input voltage. First, the voltage of the charging capacitor is dropped to a point that is low enough to turn off the inverter. The output voltage of the inverter 丨 6 at node 1 丨 8 is therefore 1237943 high, and follows the rising voltage supply source 105. Therefore, at 2 5, the voltage supply source 105 is connected to the gate of the transistor 124 via the inverter 116. When the private voltage supply source 105 rises above the threshold voltage of the transistor 24, the transistor 1% is turned on and the ground terminal 108 is connected to the node 126, which is the input of the inverter 128 and therefore at 220 'transistor 1 The gate of 24 is connected to the ground terminal 08. Then at 225, the input of inverter 128 is connected to ground terminal 经由 via transistor 24. Because the output of the inverter 28 is a power-on reset signal, coupling the input of the inverter 128 to the ground terminal 108 can initialize the nodes of the circuit that determines the output voltage of the output node. Therefore, the output of the inverter 128 is connected to the voltage supply source 105. At 230, the leading part of the power-on reset signal 13 appears at the output node of the power-on reset circuit. The power-on reset signal 130 is received by the transistor 132 and turns on the crystal 132. The transistors 134, 136, and 38 connected in series as rain resistance nodes M0 are connected to the private ground terminal 电 through transistors] 32, i 34, i 36, and i 38. Node 14 is connected to the gates of transistors 144 and 146. Transistors ⑷ and 46 are voltage detectors used as a trailing part of the power-on reset signal, and are connected to the ground terminal 08. Therefore, at 235, the input of the signal source circuit of the trailing part of the power-on reset signal is connected to the ground terminal 08. At 240 = ^ at this time, the voltage at the node 140 is lower than the voltage of the source circuit of the trailing portion of the power-on reset signal. Because the voltage at the node at this time is lower than the voltage at this disconnection point, via the transistor 48, the voltage of the node]% follows the voltage supply source | 05, and the transistor 148 is The low voltage (connected to the ground terminal 8) of node 26 is turned on. The inverter [η] takes the node quotient and 50 quotient voltage as the input, and transmits the voltage of the ground terminal iQ8 as the output. Therefore, the output of the inverter 52 corresponds to the signal from the transistor 24, and it corresponds to the leading part before the reset signal is turned on. A private 1237943 ^ 250, the voltage of the voltage supply source 05 continues to rise. At%, the node Η2 of || continues to rise as the capacitor ⑽ connected to the capacitor continues to charge. At 60 gp, the voltage at point i 12 exceeds the inverter]} 6 cut-off point. The output voltage of the inverter U6 at the node 1 1 8 drops to a low value after being connected to the ground terminal 108. This makes the transistor! The voltage of the gate of 24 is lower than the threshold of the transistor 124 and the transistor 24 is turned off. Therefore, at 265, the circuit of the leading part for generating the power-on reset signal is isolated from the power-on reset signal. When the voltage of the voltage supply source 105 continues to rise, the transistor 142 is turned on, and the point M0 becomes connected to the voltage supply source 105 through the transistor 142. Section, accounted for 140 series connected to the transistor between 144 and 146. Transistors 144 and 6. As one of the detectors used for the power-on reset reset follow-up, use an electrical detector and connect it to the ground terminal. Therefore, at 27 (), the input of the signal source circuit of the trailing portion of the power-on reset signal is connected to the voltage supply source 05. When the voltage of the voltage supply source 105 rises sufficiently, at 275, the input voltage of the signal source circuit used by the trailing portion of the power-on reset signal is increased to exceed the disconnection point of the signal source circuit. The output voltage of the signal source at node 150 is coupled to ground and reduced. The inverting H 152 receives the low voltage of the node 15 as an input, and the high voltage of the passed voltage supply source 105 as an output to the node %. The inverter 128 receives the high voltage at the node m as an input and transmits the low voltage of the ground terminal 108 ° as an output. The low voltage output from the inverting n 128 is the power on and resets the trailing part of m Therefore, the trailing part of the "on 28" power-on reset signal appears at the output node of the power-on reset circuit.
