摘要： A pulse width modulator includes an amplifier module, a comparator module, and a filter module. The amplifier module receives a feedback voltage signal from a passive network, and generates first and second non-inverted voltage signals and first and second inverted voltage signals in response to the feedback voltage signal. The comparator module receives the first and second non-inverted voltage signals and the first and second inverted voltage signals, and provides first and second differential voltage signals corresponding to the first and second non-inverted voltage signals and the first and second inverted voltage signals. The filter module is coupled between the amplifier module and the comparator module, and is operable so as to attenuate high frequency components of the first and second non-inverted voltage signals. As such, the presence of noise in the feedback voltage signal does not affect differential operation of the comparator module.
