Abstract
An amplifier includes a first amplification circuit, a second amplification circuit including first and second amplification transistors controlled by the first amplification circuit to generate first and second output signals and a bias transistor turned on based on a bias signal to generate the first output signal, a filter circuit including a bias capacitor connected to the first amplification transistor and the bias transistor to generate the first bias signal using a first bias voltage, and a feedback circuit configured to receive the first and second output signals and output a feedback signal that adjusts an average of the first and second output signals to correspond to a reference signal, to the first amplifier. The filter circuit adjusts a voltage of the bias capacitor such that a voltage of the bias capacitor when the amplifier is disabled corresponds to a voltage of the bias capacitor when the amplifier is enabled.
