Claim 0:
1. A power amplifier, comprising:
a power switching circuit configured to receive a first voltage and a second voltage, and provide the first voltage or the second voltage according to an operation mode of the power amplifier;
a driver circuit coupled to the power switching circuit, wherein the driver circuit is configured to operate according to the first voltage or the second voltage and generate a driving signal according to an input signal; and
an amplifier circuit coupled to the power switching circuit and the driver circuit, wherein the amplifier circuit is configured to operate according to the first voltage or the second voltage and generate an output signal according to the driving signal,
wherein when the operation mode of the power amplifier is a Wi-Fi mode, the power switching circuit provides the first voltage to the driver circuit and the amplifier circuit, wherein when the operation mode of the power amplifier is a Blue-tooth mode, the power switching circuit provides the second voltage to the driver circuit and the amplifier circuit.
