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.

Claim (Index 1):
An amplifying device, comprising:\n a power amplifying unit which has a first input terminal, a second input terminal, an output terminal, a first power terminal and a second power terminal, wherein the first power terminal is adapted for receiving a positive power supply, the second power terminal is adapted for receiving a negative power supply, the output terminal is adapted for receiving a drive signal; a power supply unit which has a control terminal, a first output terminal for providing the positive power supply and a second output terminal for providing the negative power supply, wherein the first output terminal of the power supply unit is connected with the first power terminal of the power amplifying unit, the second output terminal of the power supply unit is connected with the second power terminal of the power amplifying unit; and a mode control unit which has a first sampling terminal, a second sampling terminal, a third sampling terminal and an output terminal, wherein the first sampling terminal is connected with the first output terminal of the power supply unit, the second sampling terminal is connected with the second output terminal of the power supply unit, the third sampling terminal is connected with one of the first input terminal, the second input terminal and the output terminal of the power amplifying unit, the output terminal of the mode control unit is connected with the control terminal of the power supply unit, the mode control unit controls a working mode of the power supply unit based on the drive signal and an output voltage of the power supply unit, wherein: if the power supply unit works in a first working mode, the positive power supply and the negative power supply respectively have a first positive voltage and a first negative voltage; if the power supply unit works in a second positive working mode, the positive power supply and the negative power supply respectively have a second positive voltage and the first negative voltage; if the power supply unit works in a second negative working mode, the positive power supply and the negative power supply respectively have the first positive voltage and a second negative voltage; the second positive voltage is larger than the first positive voltage, and the second negative voltage is larger than the first negative voltage.
