Abstract: In a pulse generator circuit,the output and stability of the system are affected by stray parameters. In order to improve the quality of the output waveform,restrain the oscillation of the output and ensure components long-term reliable operation,it is necessary to analyze and compensate stray parameters in the pulse generator circuit. Through analyzing the actual waveform of the output,a stray parameter module for the pulse generator circuit and a new method to analyze and compensate stray parameters in the pulse generator circuit are introduced in this paper. Simulation results reflect the actual waveform accurately and no overshoot of the output is achieved after joining the compensation circuit.
