Abstract
A power amplifier includes a power switching circuit, a driver circuit, and an amplifier circuit. The power switching circuit is 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. The driver circuit is coupled to the power switching circuit. 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. The amplifier circuit is coupled to the power switching circuit and the driver circuit. 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.
