Claim 13:
14. A power amplifying method, comprising:
receiving, by a power switching circuit of a power amplifier, a first voltage and a second voltage, and proving, by the power switching circuit, the first voltage or the second voltage according to an operation mode of the power amplifier;
generating, by a driver circuit of the power amplifier, a driving signal according to an input signal, wherein the driver circuit operates according to the first voltage or the second voltage; and
generating, by an amplifier circuit of the power amplifier, an output signal according to the driving signal, wherein the amplifier circuit operates according to the first voltage or the second voltage,
wherein proving, by the power switching circuit, the first voltage or the second voltage according to the operation mode of the power amplifier, further comprising:
providing, by the power switching circuit, the first voltage to the driver circuit and the amplifier circuit when the operation mode of the power amplifier is a Wi-Fi mode; and
providing, by the power switching circuit, the second voltage to the driver circuit and the amplifier circuit when the operation mode of the power amplifier is a Blue-tooth mode.
