[0025] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] Existing high-speed digital circuits directly generate narrow pulses through high-speed sampling and FPGA internal algorithms. Although pulse control can be achieved, there may be limitations in clock stability and signal purity, especially in extremely high-frequency applications where it is difficult to meet the requirements. Although dedicated pulse generators have simple hardware circuits, they are greatly affected by temperature and process parameters, making it difficult to achieve precise parameter control and long-term stability. It can be seen that the existing pulse generation methods have limitations in the adjustability of pulse width and edge sharpness, making it difficult to achieve stable narrow pulse output. Moreover, phase jitter and synchronization issues between modules in the existing pulse generation methods will adversely affect the quality of the final generated pulse signal. In addition, the existing technology lacks a real-time adjustable solution for controlling pulse period and width, making it difficult to meet the requirements of diverse testing and application scenarios.

[0027] Based on this, an embodiment of the present invention provides a pulse generation system that can generate stable fast-edge narrow pulses.

[0028] Figure 1 FIG. 1 is a schematic diagram of a structure of a pulse generating system provided in an embodiment of the present invention. Figure 1 As shown, the pulse generation system includes a controller 1, a digital phase locked loop (PLL) 2, a limiting amplifier 3 and a pulse generation feedback device 4; The pulse generation feedback device 4 includes a first splitter 41, a delay module 42, an XOR module 43, a second splitter 44 and a feedback processing module 45; the controller 1 is connected to the digital phase-locked loop 2, the delay module 42 and the feedback processing module 45 respectively; The digital phase-locked loop 2 is connected to the limiting amplifier 3, the limiting amplifier 3 is connected to the input end of the first splitter 41, and the output end of the first splitter 41 is connected to the input ends of the delay module 42 and the XOR module 43 respectively; The delay module 42 is connected to the input end of the XOR module 43, and the output end of the XOR module 43 is connected to the input end of the second splitter 44; The output end of the second splitter 44 is connected to the feedback processing module 45 and the controller 1 respectively; the feedback processing module 45 is connected to the controller 1; The output end of the second splitter 44 is also used to output a target pulse signal.

[0029] Specifically, the controller can control the digital phase-locked loop (DPLL) to generate a highly stable sinusoidal signal, which is a digital differential signal, thereby ensuring the anti-interference capability of the pulse generation system.

[0030] This sinusoidal signal is converted by a limiting amplifier into a differential square wave signal with a fixed duty cycle. This ensures that the differential square wave signal exhibits fast-edge characteristics, namely, sharp edges and short rise / fall times, reaching the picosecond (ps) to nanosecond (ns) range. This fixed duty cycle can be set as needed and is not specifically limited here. For example, the fixed duty cycle can be set to a value range of 40%-60%, or other ranges.

[0031] The first splitter may include an input end and multiple output ends. The number of output ends of the first splitter may be set as needed, and may be set to two here.

[0032] The input end of the first splitter is used to access the differential square wave signal. The first splitter can copy the differential square wave signal into two paths, namely the first differential signal and the second differential signal, and transmit the first differential signal and the second differential signal to the input ends of the delay module and the XOR module respectively through the two output ends.

[0033] The delay module can be a precisely designed data delay line. The delay module can delay the first differential signal, that is, introduce a delay into the first differential signal to obtain a delayed differential signal, so that there is a phase difference between the delayed differential signal and the second differential signal.

[0034] It is understood that the delay module can be controlled by a controller, making the delay introduced in the first differential signal controllable, thereby creating a controllable phase difference between the delayed differential signal and the second differential signal. As a result, the phase difference between the delayed differential signal and the second differential signal can be dynamically adjusted by the controller according to specific needs, allowing the delayed differential signal and the second differential signal to be precisely aligned or staggered at predetermined times, thereby meeting the narrow pulse requirements of the output target pulse signal in different application scenarios. Here, narrow pulse refers to a pulse signal with a pulse width typically on the order of nanoseconds (ns) to microseconds (µs).

[0035] The XOR module includes two input terminals and one output terminal. The two input terminals are respectively connected to the second differential signal and the delayed differential signal. The XOR module performs an XOR operation on the connected second differential signal and the delayed differential signal, and uses the phase difference between the second differential signal and the delayed differential signal to generate an initial pulse signal, and outputs it through the output terminal of the XOR module.

[0036] The initial pulse signal is high level only when the level states of the second differential signal and the delayed differential signal are different. When the level states of the second differential signal and the delayed differential signal are the same, the initial pulse signal is low level. Figure 2 As shown, D0 is the second differential signal, D1 is the delayed differential signal, and the initial pulse signal output after the two pass through the XOR module is XOR OUT.

[0037] The second splitter includes an input end and multiple output ends. The number of the output ends of the second splitter can be set as needed. For example, the second splitter can include three output ends.

[0038] The input end of the second splitter is used to receive the initial pulse signal and copy the initial pulse signal into three paths, namely the first pulse signal, the second pulse signal and the third pulse signal, and output the first pulse signal as the target pulse signal through one of the output ends, and transmit the second pulse signal and the third pulse signal to the feedback processing module and the controller respectively through the remaining two output ends.

[0039] The feedback processing module can process the second pulse signal to obtain the analog signal DC component and transmit the analog signal DC component to the controller. At the same time, the controller receives the analog signal DC component and also receives the third pulse signal output by the second splitter. The controller can then identify the pulse width of the initial pulse signal based on the received analog signal DC component, determine the repetition period of the initial pulse signal through the third pulse signal, and perform closed-loop feedback control on the digital phase-locked loop and delay module based on the pulse width and repetition period of the initial pulse signal to ensure the fast-edge narrow pulse width characteristics of the output target pulse signal.

[0040] In particular, the pulse generation feedback device may include only the first splitter, the delay module, and the XOR module, without either the feedback processing module or the second splitter. In this case, although closed-loop feedback control cannot be achieved, the target pulse signal can still be generated as a fast-edge narrow pulse.

[0041] like Figure 3 As shown, the controller 1 is connected to the digital phase-locked loop 2 and the delay module 42 respectively.

[0042] The digital phase-locked loop 2 is connected to the limiting amplifier 3 , the limiting amplifier 3 is connected to the input end of the first splitter 41 , and the output end of the first splitter 41 is connected to the input ends of the delay module 42 and the XOR module 43 respectively.

[0043] The delay module 42 is connected to the input end of the XOR module 43 , and the output end of the XOR module 43 is used to output the target pulse signal.

[0044] The pulse generation system provided in an embodiment of the present invention includes: a controller, a digital phase-locked loop (DPL), a limiting amplifier, and a pulse generation feedback device. The pulse generation feedback device includes a first splitter, a delay module, an XOR module, a second splitter, and a feedback processing module. By combining a digital phase-locked loop (DPL) and analog delay control, the pulse generation system achieves fine pulse width control while maintaining high frequency stability, taking into account the accuracy of digital logic and the flexibility of analog control. Moreover, a high-quality differential square wave signal is generated by the limiting amplifier, and then combined with the delay module, fine phase difference control is achieved, thereby generating a target pulse signal with a narrow pulse width, fast edges, and precise pulse width. In addition, by controlling the digital phase-locked loop and the delay module through the controller, the pulse width can be flexibly adjusted, and the pulse period can be controlled to meet the diverse requirements of pulse parameters in different application scenarios. The introduction of the feedback processing module can also provide the controller with real-time monitoring and correction functions, effectively offsetting the effects of environmental changes and drift of various components in the pulse generation system. This pulse generation system not only simplifies the complex circuitry used to generate traditional fast-edge, narrow pulses, but also enhances anti-interference capabilities and timing accuracy by utilizing differential signaling and feedback processing modules, combined with a controllable delay module. This provides a reliable and high-performance solution for high-speed digital communications, timing, and signal processing. Each component in this pulse generation system is independent of each other, facilitating expansion.

[0045] Based on the above embodiments, Figure 4 As shown, the pulse generating system further includes: a third splitter 5; the number of the pulse generating feedback device 4 includes multiple; The input end of the third splitter 5 is connected to the limiting amplifier 3; The output end of the third splitter 5 is connected to the input end of the first splitter 41 in the plurality of pulse generating feedback devices 4 respectively; The controller 1 is respectively connected to the delay module 42 and the feedback processing module 45 in the plurality of pulse generating feedback devices 4 .

[0046] Specifically, the third splitter can be used to expand the pulse generation system so that it can synchronously output multiple target pulse signals, which is suitable for multiple synchronous target pulse signal generation scenarios and larger-scale integrated test platforms.

[0047] It is understandable that the number of output target pulse signals that the pulse generation system can support can be determined by the number of output terminals of the third splitter. Figure 4 In the example, the third splitter including one input terminal and three output terminals is taken as an example.

[0048] Based on the above embodiment, the feedback processing module includes a filter and an analog-to-digital converter; the filter is connected to the analog-to-digital converter; The filter is connected to the output end of the second splitter; The analog-to-digital converter is connected to the controller.

[0049] Specifically, in an embodiment of the present invention, a feedback processing module can be formed by connecting a filter and an analog-to-digital converter. The filter can convert the second pulse signal output from the output end of the second splitter into a digital signal DC component, which refers to the average value of the periodic second pulse signal. The analog-to-digital converter can convert the digital signal DC component into an analog signal DC component. In this way, it can be transmitted to a controller, which receives and identifies the pulse width of the initial pulse signal.

[0050] In the embodiment of the present invention, a feedback processing module is constructed by using a filter and an analog-to-digital converter, which has a simple structure and low cost.

[0051] On the basis of the above embodiment, the pulse generating feedback device further includes a driving module; The driving module is connected to the output end of the second splitter; The driving module is used to adjust the target pulse signal.

[0052] Specifically, the pulse generation feedback device may also include a driver module, which may be a voltage-controlled amplifier for adjusting the input. This adjustment may include dynamic amplitude control, dynamic range compression / expansion, pulse waveform adjustment, etc. Dynamic amplitude control may include variable gain adjustment or automatic gain control (AGC). Variable gain adjustment refers to adjusting the amplitude of the target pulse signal in real time through an external control voltage. For example, in radar or communication systems, the intensity of the target pulse signal is increased or decreased as needed. Automatic gain control refers to stabilizing the amplitude of the target pulse signal. Even if the amplitude of the target pulse signal fluctuates, the amplitude of the target pulse signal can be controlled to remain constant, preventing overload or distortion of the target pulse signal.

[0053] Dynamic range compression / expansion can include compressing high-amplitude pulses or enhancing weak pulses. High-amplitude pulse compression limits the maximum amplitude of the target pulse signal to prevent overload of subsequent circuits. Weak pulse enhancement increases the visibility of the minimum amplitude of the target pulse signal to improve the signal-to-noise ratio.

[0054] Pulse waveform adjustment can include edge control and amplitude equalization.

[0055] In the embodiment of the present invention, the target pulse signal is adjusted by the driving module, so that the performance of the adjusted target pulse signal can be improved.

[0056] Based on the above embodiment, the digital phase-locked loop is used to generate a sinusoidal signal, and the limiting amplifier is used to convert the sinusoidal signal into a differential square wave signal with a fixed duty cycle.

[0057] Specifically, in the embodiment of the present invention, a digital phase-locked loop is used to generate a sinusoidal signal, and the sinusoidal signal is a digital differential signal, which can ensure the anti-interference capability of the pulse generation system.

[0058] The limiting amplifier can convert the sinusoidal signal into a differential square wave signal with a fixed duty cycle, providing a basis for generating a target pulse signal with narrow pulse width, fast edge and precise pulse width.

[0059] On the basis of the above embodiment, the fixed duty cycle is 50%, which can further ensure that the target pulse signal has a fast edge characteristic.

[0060] Based on the above embodiment, the pulse width of the target pulse signal can be controlled by the controller through the delay amount of the delay module. By finely adjusting the delay amount of the delay module, the generation of an extremely narrow target pulse signal can be achieved.

[0061] The repetition period of the target pulse signal can be controlled by the controller through the output frequency of the digital phase-locked loop, which makes the entire pulse generation system extremely flexible and controllable.

[0062] Combined with the feedback processing module, the controller can detect the pulse width and repetition period of the initial pulse signal in real time, and achieve temperature compensation, jitter suppression and long-term stability optimization by closed-loop adjusting the delay amount of the delay module and the output frequency of the digital phase-locked loop.

[0063] like Figure 5 As shown, based on the above embodiment, an embodiment of the present invention provides a pulse generating method, including: S1, controlling a digital phase-locked loop to generate a sinusoidal signal, the sinusoidal signal is passed through a limiting amplifier to generate a differential square wave signal with a fixed duty cycle, the differential square wave signal is split into a first differential signal and a second differential signal through a first splitter; S2, controlling the delay module to perform delay processing on the first differential signal to obtain a delayed differential signal; performing XOR processing on the second differential signal and the delayed differential signal via an XOR module to obtain an initial pulse signal, the initial pulse signal is divided into a first pulse signal, a second pulse signal and a third pulse signal via a second splitter, the first pulse signal is used as a target pulse signal output, and the second pulse signal is processed via a feedback processing module to obtain a DC component of an analog signal; S3, receiving the third pulse signal and the DC component of the analog signal, determining the pulse width and repetition period of the initial pulse signal based on the third pulse signal and the DC component of the analog signal, and performing feedback control on the limiting amplifier and the delay module based on the pulse width and repetition period.

[0064] Specifically, the pulse generation method provided in the embodiment of the present invention is executed by a controller in the pulse generation system. The controller can be a micro control unit or a computer. The computer can be a local computer or a cloud computer. The local computer can be a computer, a tablet, etc., which is not specifically limited here.

[0065] The controller executes step S1 to control the digital phase-locked loop (DPLL) in the pulse generation system to generate a sinusoidal signal. The sinusoidal signal is then passed through a limiting amplifier connected to the DPLL to generate a differential square wave signal having a fixed duty cycle. The fixed duty cycle can be set as needed and is not specifically limited herein. For example, the fixed duty cycle can be preferably 50%.

[0066] The differential square wave signal is divided into a first differential signal and a second differential signal through a first splitter connected to the limiting amplifier.

[0067] The controller executes step S2 to control the delay module in the pulse generating system to perform delay processing on the first differential signal to obtain a delayed differential signal.

[0068] The second differential signal and the delayed differential signal are respectively input into the XOR module for XOR processing to obtain the initial pulse signal. The initial pulse signal passes through the second splitter to obtain the first pulse signal, the second pulse signal and the third pulse signal.

[0069] The first pulse signal can be directly output as the target pulse signal, and the second pulse signal is fed back through the feedback processing module to obtain the DC component of the analog signal.

[0070] It is understandable that the execution order of steps S1 and S2 can be determined as needed. For example, step S1 can be executed first and then step S2, or step S2 can be executed first and then step S1, or steps S1 and S2 can be executed simultaneously. No specific limitation is made here.

[0071] Finally, step S3 is executed to receive the DC component of the analog signal obtained by the feedback processing module and the third pulse signal obtained by the second splitter, and the third pulse signal is used to determine the repetition period of the initial pulse signal, and the DC component of the analog signal is used to determine the pulse width of the initial pulse signal. Then, the pulse width and repetition period can be used to generate control instructions to perform feedback control on the limiting amplifier and the delay module respectively.

[0072] The pulse generation method provided in the embodiment of the present invention, through the combination of a digital phase-locked loop and analog delay control, enables the pulse generation system to achieve fine pulse width control while maintaining high frequency stability, taking into account the accuracy of digital logic and the flexibility of analog control. Moreover, a high-quality differential square wave signal is generated by a limiting amplifier, and then combined with a delay module to achieve fine phase difference control, thereby generating a target pulse signal with a narrow pulse width, fast edges, and precise pulse width. In addition, through the control of the digital phase-locked loop and the delay module by the controller, it is possible to flexibly adjust the pulse width and control the pulse period to meet the diverse requirements of pulse parameters in different application scenarios. The introduction of the feedback processing module can also provide the controller with real-time monitoring and correction functions, effectively offsetting the effects of environmental changes and drift of components in the pulse generation system.
