Power amplification equipment

摘要

A power amplification apparatus receiving in input an enable signal (En) and an input square wave signal (C) is described. The apparatus comprises a device (6) receiving the input square wave signal (C) and the enable signal (En) and which produces a new enable signal (Ens) of the apparatus which is synchronized with a rise or down front of the input square wave signal (C), so that an output square wave signal (Vo) of the apparatus, which is normally shifted of a certain period fraction with respect to the square wave signal (C) in input to the apparatus, has the first (Ti) and the last (Tf) pulses which have a duration equal to a period fraction of the output square wave signal (Vo). <IMAGE>
