Description

Intermittent operation circuit and modulating device

Technical field

The present invention relates to intermittent operation circuit, relate in particular to and make oscillating circuit, amplifying circuit and frequency multiplier circuit carry out intermitten, and, (rise: rise) and from the transient state of stable state till the end of intermitten (descend: the fall) intermittent operation circuit of lacking very much until the transient state till the stable state from the beginning of intermitten.In addition, the present invention relates to have the modulating device of such intermittent operation circuit.

Background technology

In the past, as UWB (Ultra Wide Band: one of technology ultra broadband), carried out the communication of using short pulse signal (short-pulse signal) and the development of radar in the past.As making short pulse signal become the signal of the band component that only has expectation, have: carry out the method that frequency band limits is only extracted specific frequency component by the filter pulse signals, and make oscillating circuit carry out intermitten, thereby obtain the method for short pulse by the control signal of input pulse.In addition, also have by control signal to be input to amplifying circuit and frequency multiplier circuit makes circuit carry out intermitten, thereby generate method with the high interval corresponding short pulse of the voltage level of control signal pulse feature.

The negative-resistance device (negative resistance element) that oscillating circuit comprises the active element (active component) of transistor etc., is made of tunnel diode (tunnel diode) and operational amplifier (operational amplifier), and resonant circuit.Use Fig. 1, the intermittent operation circuit in the past that uses the tunnel diode oscillating circuit is described.In intermittent operation circuit 10, pass through inductor (inductor) 12 from the control signal of control signal generation circuit 11 outputs, be imported into negative-resistance device 13.Negative-resistance device 13 has the voltage-current characteristic shown in 14 among the figure, and its voltage in the control signal of being imported is at regional 1 o'clock and vibrates, and is in the zone 2 or the failure of oscillations (referring to patent documentation 1) in regional 3 o'clock.

Yet, in above-mentioned circuit structure in the past, when the control signal with pulse feature is input to circuit, because of existing parasitic capacitance in circuit (parasitic capacitance) and stray capacitance (straycapacitance) make control signal waveform not precipitous (rounded).Therefore, following problem takes place: exist from input control signal to begin the time (rise time) till stable state and stop the time (fall time) until vibration stops of beginning from control signal, its result, the rising of output waveform and decline are not precipitous.In the situation that has adopted tunnel diode as negative-resistance device, in using transistorized oscillating circuit, too above-mentioned problem can take place not only.And, be not limited to oscillating circuit, when making amplifying circuit and frequency multiplier circuit carry out intermitten also same problem can take place.

In the past, as a method that addresses this problem, as shown in Figure 2, used as control signal that to have produced the method for waveform 21 of overshoot (overshoot) 22 and Xia Chong (undershoot) 23 at rising edge and trailing edge well-known.Because by overshoot 22 with down towards 23, can offset and result from waveform not precipitous of existing input capacitance (interterminal capacitance and stray capacitance) in oscillating circuit, amplifying circuit and the frequency multiplier circuit, so can shorten the rise time and the fall time of output waveform effectively.

But based on this method, the slope ground that output waveform can not surpass control signal rises at a high speed, and, be difficult to carry out desirable waveform shaping.In order to carry out waveform shaping easily, the technology of using speed-up condenser (speed-up capacitor) to produce overshoot and dashing down is well-known, but owing to have self-resonant frequency (self-resonant frequency) at capacitor, there is boundary on overshoot that is produced and the following frequency component of dashing, so control signal can not the very precipitous waveform of oblatio.Therefore, shown in the waveform among Fig. 3 31, the oblatio slow waveform that rises and descend though have the charge effect of (charge) of input capacitance, can not get the rising characteristic of ns (nanosecond-order).Especially under the situation that is intermittent oscillation circuit, come from the delay of the feedback circuit in the circuit, be difficult to generate the short pulse that can be applicable to UWB.

As solution to the problems described above, as shown in Figure 4, existence is based on the timing waveform from timing generation circuit 44, the starting that time width is short promotes that signal is input to the technology of oscillating circuit 43, and described starting promotes signal to be signal (referring to patent documentation 2) 41 that produce by the standard signal generation device, that have the frequency component identical with the oscillating circuit 43 that comprises quartz crystal unit 42.Thus, can when the rising of output waveform, promote the growth of vibration, thereby be effective in the high speed starting of oscillations.

(execution mode 1)

(1) overall structure

The structure of the intermittent operation circuit of expression embodiments of the present invention 1 among Fig. 5.Intermittent operation circuit 100 comprises: control

signal generation circuit

101 and 102; Timing adjusting circuit 103; Waveform combiner circuit 104; Impedance adjustment circuit 105; And active circuit 106.Active circuit 106 is the circuit that comprises the active element of transistor etc., for example is oscillating circuit.

Control signal generative circuit 101 generates control signal S1, and control signal generation circuit 102 generates control signal S2.Here, the signal waveform of control

signal generation circuit

101 and 102 control signal S1 that exported and S2 supposes below that for arbitrarily it describes for impulse waveform.

Pass through

terminal

110 and 111 respectively from the control signal S1 and the S2 of control

signal generation circuit

101 and 102 outputs, be imported into timing adjusting circuit 103.The time location of 103 couples of control signal S1 of timing adjusting circuit and S2 is adjusted, and adjusted control signal S1A of time and S2A are passed out to waveform combiner circuit 104.104 couples of control signal S1A of waveform combiner circuit and S2A synthesize, and by terminal 107, the control signal S3 after synthetic are passed out to impedance adjustment circuit 105.By the adjusted control signal S4 of impedance adjustment circuit, be output to active circuit 106 by terminal 108.Active circuit 106 is based on control signal S4 Be Controlled, and output short pulse signal S5.

At the state of each control signal shown in Fig. 6 A presentation graphs 5, and represent the example of the state of the short pulse signal that active circuit is exported at Fig. 6 B.In Fig. 6 A and Fig. 6 B, the longitudinal axis is voltage, and transverse axis is the time.

Then, use Fig. 5, Fig. 6 A and Fig. 6 B that the action of the intermittent operation circuit 100 of present embodiment is described.

Control signal generation circuit 101 output control signal S1, and control signal generation circuit 102 output control signal S2.

Control signal S1 is action beginning and the release that is used to control active circuit 106, and the vibration that is used for the action by active circuit 106 is output is (hereinafter referred to as " stable vibration ".At active circuit 106 is under the situation of oscillating circuit, and vibration vibration is equivalent to this vibration, and under the situation that be amplifying circuit and frequency multiplier circuit, amplifies the back and is equivalent to this vibration with the dither that carries out after the frequency multiplication) control signal exported off and on.The magnitude of voltage V of control signal S1 ₁Be the required magnitude of voltage of action that the active element that comprised in the active circuit 106 is expected, and period T is to make circuit carry out the time of intermitten.But, the impedance of the transmission path of being propagated according to control signal S1, time T can be elongated or be shortened sometimes.

Control signal S2 is used to make active circuit 106 to produce the control signal of ring vibration, it rises than control signal S1 precipitous (comprising up to higher frequency component), its slope depends on the performance (mutual conductance (transconductance) gm and circuit impedance etc.) of active circuit 106 and the relation between the impedance adjustment circuit 105, time width Δ T is the cycle of the ring vibration that produced, perhaps close with it value.Magnitude of voltage V ₂It is the value that to control the amplitude of the ring vibration that is produced by this value.

In addition, the control signal S2 charging facilitating the interterminal capacitance of active element and be present in the stray capacitance in the circuit by its electric energy.For generation condition and the slope of control signal S2 and the relation between active circuit 106 and the impedance adjustment circuit 105 of ring, will narrate in the back.

Control signal S1 and S2 are adjusted time location by timing adjusting circuit 103, adjusted control signal S1A of the time that becomes and S2A.

Here, the time difference τ 1 in Fig. 6 A is adjusted, so that ring vibration that active circuit 106 is generated and stable vibration can continue output, and it regularly can middle on the drawing board decision.In addition, though in Fig. 6 A, time difference τ 1 expression control signal S2A is later than control signal S1A in time, is not limited to this, and according to the performance of active circuit 106, the opposite time relationship of oblatio also is τ 1=0 (zero) sometimes sometimes.In the circuit of reality, timing adjusting circuit 103 can be realized simply by the circuit of different length is long.

Control signal S1A and S2A from timing adjusting circuit 103 outputs carry out waveform by waveform combiner circuit 104 and become control signal S3.Control signal S3 is imported into active circuit 106 by impedance adjustment circuit 105.

Impedance adjustment circuit 105 is the passive circuits that for example are made of resistive element, sensing element, capacity cell and microstrip line (microstrip line) etc., and is the circuit that conversion is carried out in the impedance to from terminal 107 active circuits 106 ends the time.

In the present embodiment, be set at the relation between slope, active circuit 106 and the impedance adjustment circuit 105 of control signal S2 as follows.That is to say, in the present embodiment, the circuit constant of decision impedance adjustment circuit 105 and the slope of control signal S2, so that damping constant (damping constant) K that determines based on the impedance of the circuit that comprises impedance adjustment circuit 105 and active circuit 106 is less than 1 (ring generation condition), and make that the frequency of the ring vibration that produced is the value identical or close with the frequency of stable vibration.

Here, damping constant K becomes less than 1 by its value and to make circuit produce the ring vibration, when establishing s and be the separating of Laplace transform (Laplace transform) in the transfer function of circuit, can be expressed from the next.

s ²+2Kωs+ω ²＝0.........(1)

Because when circuit has been transfused to the steeper control signal of slope, ring vibration is based on being determined from the slope of the impedance of the circuit of input terminal and control signal, so be different from control signal S1A, control signal S2A can not make waveform not facilitate the ring vibration with the stray capacitance that is present in the circuit because of the interterminal capacitance of active element not precipitously.Therefore, for the frequency of the ring vibration (Fig. 6 B (a)) that occurs at active circuit 106, the slope by decision impedance adjustment circuit 105 and control signal S2 can make it become the desired frequency component.

In addition, because the amplitude of ring vibration determined with the magnitude of voltage of control signal based on the impedance of the circuit of the steeper control signal of input slope, therefore by determining the magnitude of voltage V of impedance adjustment circuit 105 and control signal S2 ₂, can control the amplitude that ring is vibrated.In addition, because the occurring principle of stable vibration (Fig. 6 B (b)) is known technology, so omit its explanation.

Here, with the timing of aforesaid τ 1 control signal S1 and S2 are carried out the timeliness adjustment, to stable vibration (Fig. 6 B (b)) vibration is continued thereby can vibrate (Fig. 6 B (a)) from ring by timing adjusting circuit 103.And then, when active circuit 106 is oscillating circuit, with the timing of aforesaid τ 1 control signal S1 and S2 are carried out the timeliness adjustment by timing adjusting circuit 103, can access the effect that is promoted the growth of vibration by ring, signal (Fig. 6 B (c)) is output so rise faster.

(2) control signal generation circuit

Because the structure of control signal generation circuit 101 is suitable for known technology and gets final product, so omit its explanation.Here, control signal generation circuit 102 is described.

The configuration example of expression control signal generation circuit 102 among Fig. 7.In addition, in Fig. 8, be illustrated in the situation of the variation of the control signal in the control signal generation circuit of Fig. 7.In Fig. 8, the longitudinal axis is voltage, and transverse axis is the time.

As mentioned above, control signal generation circuit 102 be set to produce have arbitrarily rise and descending slope, magnitude of voltage is V ₂Control signal S2.

As shown in Figure 7, control signal generation circuit 102 have as control signal generation circuit 101 set by technique known, with the signal generating source 301 of signal S10 output.At breakout 302, signal S10 is branched to two signals.One side's signal is imported into delay circuit 303, is delayed Δ T.Here, Δ T is the time Δ T shown in Fig. 6 A.The signal that has postponed Δ T is imported into circuit for reversing (inverting circuit) 304, and the positive and negative of voltage is inverted, thereby obtains reverse signal S11 as shown in Figure 8.Reverse signal S11 is synthetic with the signal the opposing party of 302 branches of breakout by combiner circuit 305, obtains composite signal S12 as shown in Figure 8 thus.Composite signal S12 is imported into and has used rectification circuit 306 diode with rectified action, clipping circuit and rectification circuit etc., thereby final control signal S2 is output.By signal generating source 301, can set the slope of rising and the decline of control signal S2 in advance.

From the magnitude of voltage of signal generating source 701 outputs is V ₃Control signal S30 be imported into stopper circuit 702.For example as shown in figure 13, stopper circuit 702 is the passive circuit that comprises inductor 901, resistive element 902 and capacitor 903.By stopper circuit 702, control signal S30 becomes rising and descend and has produced the signal S31 of overshoot.The cycle Δ T of this overshoot is identical with the Δ T shown in Fig. 6 A.In addition, the magnitude of voltage V of overshoot ₂Be the magnitude of voltage V shown in Fig. 6 A ₂For Δ T, can set based on the impedance of stopper circuit 702, and for magnitude of voltage V ₂, can be based on the impedance of stopper circuit 702 and the magnitude of voltage V of control signal S30 ₃Set.Produced the control signal S31 of overshoot rising and descend, be imported into and used rectification circuits 703 diode with rectified action, clipping circuit and rectification circuit etc., be output magnitude of voltage V as control signal S2 ₃Signal component more than the perhaps close magnitude of voltage with it.For the slope of rising and the decline of control signal S2, can set based on the performance of stopper circuit 702.

In addition, though control signal S20 and control signal S30 are made as its rising and the very steep signal of decline, but if it is more slow to rise and descend, then the back level insertion drive circuit (driver circuit) at signal generating source 501 and signal generating source 701 gets final product.

(4) effect of execution mode and distortion example

As mentioned above, according to present embodiment, by using first control signal generation circuit 101, second control signal generation circuit 102, timing adjusting circuit 103, waveform combiner circuit 104, impedance adjustment circuit 105 and active circuit 106 to generate ring vibration and stable vibration, and initialization circuit constant, the magnitude of voltage of the first control signal S1 and slope and the magnitude of voltage of the second control signal S2, so that the frequency component of ring vibration and stable vibration is identical or close value, thus the rising that can realize output waveform intermittent operation circuit 100 faster.That is to say, can realize to obtain rising the intermittent operation circuit 100 of short pulse signal S5 faster.

In addition, also can adopt the structure that for example timing adjusting circuit 103 is included in first and second control signal generation circuit 101 and 102.That is to say, also can pass through first and second control

signal generation circuit

In addition, though in the above-described embodiment, the amplitude of the ring vibration of the short pulse signal S5 that generated is stipulated especially,, can be by the magnitude of voltage V of control signal S2 ₂Amplitude to ring is controlled.To accelerate in order making, preferably the amplitude of the ring vibration of short pulse signal S5 to be set at the identical or close value of amplitude with the stable vibration of active circuit 106 from the rising of the waveform of the short pulse signal S5 of active circuit 106 output.In addition, owing to determine the envelope (envelope) of output waveform by the amplitude of ring vibration, if, then do not need to be provided with channel model or specification (spec) and obtain relaxing so the amplitude of ring is set at the value of the channel band in the system specification (specifications) that the envelope that makes signal S5 satisfies wireless communication system.

In addition, though in the above-described embodiment, the magnitude of voltage of the control signal S2 that accelerates with the rising that is used to make short pulse signal S5 is on the occasion of being illustrated, even but the magnitude of voltage of control signal S2 is made as negative value, the rising of short pulse signal S5 is accelerated.Thus, the amplitude of the ring that takes place in active circuit 106 also becomes negative value.Therefore, positive and negative according to the magnitude of voltage of control signal S2 can be controlled the phase place of the output of the intermittent operation circuit 100 that comprises the ring vibration.At this moment, in control signal generation circuit 102, in Fig. 7 and Figure 11 in the back level of rectification circuit, and in Fig. 9 in the back level of Ft translation circuit, circuit for reversing need be set in addition.

In addition, though in the above-described embodiment, the rising that the control signal S2 that the rising that is used to make short pulse signal S5 is accelerated has been described is steeper, but control signal S2 also can be the signal that comprises for the required frequency component of the ring vibration with desired frequency and amplitude.

In addition, though in the above-described embodiment, illustrated that the frequency component of the control signal S2 that the rising that is used to make short pulse signal S5 is accelerated is single frequency band, also can also include the frequency component of the operating frequency of source circuit 106.

In addition, though in the above-described embodiment, the intermittent operation circuit that the rising that is used to make short pulse signal S5 is accelerated is illustrated, if but in the timing of the decline of control signal S2, the control signal that will have the absolute value of slope identical or close with control signal S2 and voltage level is input to circuit, the decline of output waveform is accelerated, and can be realized the rising of output waveform and the intermittent operation circuit faster that descends.

In addition, though in the above-described embodiment, use 105 pairs of circuit impedances of impedance adjustment circuit to adjust,, then can omit impedance adjustment circuit 105 if the circuit impedance of active circuit 106 meets the condition of expectation from input terminal 107.
