Abstract
An amplifying device includes a power amplifying unit, a power supply unit for providing the power amplifying unit with a positive power supply and a negative power supply, and a mode control unit for controlling a working mode of the power supply unit. The positive power supply and the negative power supply of the amplifying device are able to vary with an output signal thereof, which reduces the power consumption of the outputted transistors of the amplifying device, thereby improving the efficiency of the amplifying device.
