Linear power amplifier

Abstract

Abstract In this amplifier, comprising at least one bipolar transistor (1) of class B type, equipped with a so-called control electrode to which the signal to be amplified is applied, and with two so-called transfer electrodes at one of which the amplified signal is obtained, and means (3) for biasing these transistors, the biasing means comprise a generator (7) of stepwise variable biasing signals, and means (8) for controlling this generator as a function of the amplitude of the amplified signal, with a view to, at each instant, maintaining the absolute value of the voltage between transfer electrodes, for that transistor which is conducting at this instant, equal to at most a limit value DELTA V. Application to electrical signal generators. <IMAGE>
