Abstract
The present invention provides an amplifier circuit, wherein the amplifier circuit includes a DAC, an output stage and a detector. In the operations of the amplifier circuit, the DAC is arranged for performing a digital-to-analog converting operation upon a digital input signal to generate an analog signal, the output stage is arranged for receiving the analog signal to generate an output signal, and the detector is arranged for detecting a characteristic of the input signal, and referring to the characteristic of the input signal to generate at least one control signal to adjust the output stage at a zero-crossing point of the output signal.
