ABSTRACT:
An amplification circuit includes a semiconductor amplification element, a current feedback circuit that is connected to a terminal close to a ground side of the semiconductor amplification element and can control gain reduction, and a voltage feedback circuit that is connected between an input terminal and an output terminal of the semiconductor amplification element and can control feedback voltage. The feedback voltage of the voltage feedback circuit may be varied according to the gain reduction controlled by the current feedback circuit.
