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 4):
The amplifying device, as recited in  claim 1 , wherein the power amplifying unit comprises:\n a first amplifier 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 of the first amplifier is adapted for receiving the positive power supply, the second power terminal of the first amplifier is adapted for receiving the negative power supply, the output terminal of the first amplifier is adapted for providing the drive signal; a first resistor which has a first terminal and a second terminal, wherein the first terminal of the first resistor is connected with the first input terminal of the power amplifying unit, the second terminal of the first resistor is connected with the first input terminal of the first amplifier; a second resistor which has a first terminal and a second terminal, wherein the first terminal of the second resistor is connected with the second input terminal of the power amplifying unit, the second terminal of the second resistor is connected with the second input terminal of the first amplifier; a third resistor which has a first terminal and a second terminal, wherein the first terminal of the third resistor is connected with the first input terminal of the first amplifier, the second terminal of the third resistor is connected with ground; and a fourth resistor which has a first terminal and a second terminal, wherein the first terminal of the fourth resistor is connected with the second input terminal of the first amplifier, the second terminal of the fourth resistor is connected with the output terminal of the power amplifying unit; a ratio of a resistance of the first resistor to a resistance of the third resistor is equal to a ratio of a resistance of the second resistor to a resistance of the fourth resistor.
