Abstract
A bias circuit of an amplifying device including amplifying circuits and a bypass circuit responding to a first control signal, includes a first bias circuit, a second bias circuit, and a compensating circuit. The first bias circuit is configured to supply a first base bias voltage to a first amplifying circuit of the amplifying circuits in response to a second control signal. The second bias circuit is configured to supply a second base bias voltage to a second amplifying circuit of the amplifying circuits in response to a third control signal. The compensating circuit is connected to either one or both of the first bias circuit and the second bias circuit, and configured to vary an impedance in response to a fourth control signal, and compensate for either one or both of the first base bias voltage and the second base bias voltage based on the varied impedance.
