Abstract
An amplifier may include a differential pair circuit configured to generate an output signal according to a first input signal and a second input signal, a plurality of current sinks coupled between a ground terminal and the differential pair circuit, and a feedback circuit configured to sense a level of the output signal and generate a feedback signal. At least one of the plurality of current sinks is controlled according to the feedback signal.
