Abstract
A power supply device for driving an amplifier includes a first power generator, a second power generator, a charge pump and a control unit. The first power generator is used for providing a first voltage for a first power reception end of the amplifier. The second power generator is used for providing a second voltage. The charge pump is coupled between the second power generator and a second power reception end of the amplifier and is used for generating a third voltage for the amplifier according to the second voltage. The control unit is coupled to the second power generator and is used for controlling the second power generator, so as to adjust the second voltage to make the third voltage equal to a multiple of the first voltage.
