Abstract
There are provided a bias circuit and an amplifier controlling a bias voltage, the bias circuit and the amplifier including a control voltage generating unit generating a control voltage using a reference voltage, a bias voltage generating unit generating a bias voltage according to the control voltage, and a voltage drop unit dropping the bias voltage from the bias voltage generating unit to a base voltage so as to provide the base voltage to an amplifying unit, wherein the control voltage generating unit controls the control voltage according to an amplitude of a high-frequency signal input to the amplifying unit.
