Abstract
Starting from the fact that the amplitude of the basic harmonics of the current, flowing through load resistor of the class E power amplifier, is proportional to direct current flowing through the collector battery of the switching transistor, an introduction of a current mirror in emitter circuit of the transistor in whose reference branch is situated a generator of modulating voltage is proposed. It can be easily proven that the total current of this mirror, which is also the direct current of the collector battery, has the waveform of the amplitude modulated signal. This amplitude modulator is verified for performance with pSpace model. .
