摘要： Disclosed is an amplifier with which output signal distortion can be reduced, and deterioration in power efficiency can be reduced. The amplifier is provided with a power supply voltage control unit (11) that generates a voltage control signal from a simple envelope of an input signal in order to control a variable voltage power supply (12). The power supply voltage control unit (11) is composed of: a slope comparison processing unit (112) that calculates the slope required to generate a voltage control signal; a total delay time calculation unit (113) that calculates the sum of the delay times between the dots produced by the slope comparison process; and a voltage control signal generation unit (114) that generates a voltage control signal in such a manner that the waveform formed by the voltage control signal, which controls the variable voltage power supply (12), constitutes a waveform that reflects the selected slope or the sum of the slew rate and delay time. The voltage control signal is output to the variable voltage power supply (12) after being adjusted to match the timing at which the input signal is amplified by an amplifier unit (14).
