To meet the wide range of operating frequency and duty cycle adjustment, especially in high frequency and high amplitude output requirements,a field programmable gate array based on the drive and power to achieve the numerical design method of rectangular wave generator, through field- programmable gate array implementation of controlled internal counter output signal frequency and duty cycle adjustment,change the drive signal through the digital power supply voltage, enabling the output signal amplitude of the digital control. Experimental results show that the system is simple,low power consumption, output signal frequency and duty cycle adjustment range, the frequency precision, the resulting waveform is stable, distortion, anti-interference ability, high-frequency high-amplitude output to meet the special requirements.
