Abstract:
A power amplifier circuit includes a differential to single-ended converter, a gain stage circuit, a driver stage circuit, and an output stage circuit connected in series, and a bias circuit connected to a bias voltage port of the gain stage circuit for adjusting a bias voltage of the gain stage circuit. The bias voltage is adjustable to ensure low power consumption, improve the efficiency of the power amplifier circuit and prevent process, voltage and temperatures from affecting the performance of the power amplifier circuit.

Claim (Index 14):
The method of  claim 13 , wherein the bias circuit comprises:\n a first current source group including a plurality of first current sources, each of the first current sources having a first terminal connected to a power supply voltage through a switch, and a second terminal connected to the bias voltage port; a second current source group including a plurality of second current sources, each of the second current sources having a first terminal connected to the bias voltage port through a switch, and a second terminal connected to ground; and a transmission gate control unit connected to the second terminal of each of the first current source group, the first terminal of each of the second current source group, and the bias voltage port of the gain stage circuit.
