The invention discloses a power amplification circuit. The circuit comprises a switching circuit, an amplifier and a load. The switching circuit receives a first power supply voltage and a second power supply voltage. The switching circuit supplies the first power supply voltage to a first node when in a first mode and supplies the second power supply voltage to the first node when in a second mode. The amplifier receives a first input signal and a second input signal and generates a first output signal and a second output signal at the first output end and second output end. The load comprises a first inductor and a second inductor, the first inductor is connected between the first node and the first output end, and the second inductor is connected between the first node and the second output end.
