Abstract: The disclosure provides a common mode voltage dynamic modulation circuit, a method thereof and a class-D audio power amplifier. The modulation circuit includes: a signal input terminal and a common mode voltage dynamic adjustment module. The signal input terminal is used to receive an audio signal and output a differential audio signal to the common mode voltage dynamic adjustment module. The common mode voltage dynamic adjustment module is used to dynamically adjust a common mode voltage of the differential audio signal according to a preset static common mode bias and a normalized processing result of a swing of the audio signal, track an amplitude of an input audio signal in real time and obtain a continuously adjusted common mode voltage.
