摘要： The present disclosure generally relates to a PWM comparator and a class D amplifier. The PWM comparator described above introduces current feedback mechanism, basing the waveform state of received high frequency triangle signal and the level state of output signal of the PWM comparator, the hysteresis is changing dynamically. In the same resolution, the noise resistance ability of the PWM comparator described above is much better than that of the conventional PWM comparators which has a fixed hysteresis, thus the PWM comparator can work stably even if the duty cycle of output signal is nearly 100%.
