摘要：
An amplifier circuit includes a feedback loop; a former stage amplifier unit coupled to an input node of the amplifier circuit and the feedback loop for amplifying the difference between an input signal received from the input node and an output signal which comes back through the feedback loop, and outputting a first output signal; a compensating amplifier unit coupled to the former stage amplifier unit for amplifying the first output signal and outputting a second output signal; and an output stage amplifier unit coupled to the compensating amplifier unit and the feedback loop for outputting a third output signal according to the second output signal.
