Abstract
An efficient amplifying device is achieved. An amplifying device that amplifies a signal subject to amplification is configured as follows. That is, an amplifier (PA) that amplifies a signal is provided. Level control meansconverts a level of the signal subject to amplification according to the level of this signal. Power supply control meansandsupply the amplifier (PA) with a power supply voltage determined according to the level of the signal subject to amplification. The amplifier (PA) amplifies a signal at the level converted by the level control meanswith the power supply voltage supplied from the power supply control meansand
