ABSTRACT:
A power amplifier is provided with a peak-holding means for holding, for a given period of time, a peak value of an input signal or an output signal of a power amplifying element there of and is provided also with a switching means for switching, to a selected value in accordance with an output from the peak-holding means, a dc power supply voltage which is supplied to said power amplifying elements. Such amplifier is able to enhance the power efficiency of the power amplifier as well as to reduce switching noises and to reduce the development of distortions.
