H03F3/423 - CPC Classification

Classification description:

Amplifiers with only discharge tubes or only semiconductor devices as amplifying elements; Amplifiers with two or more amplifying elements having their dc paths in series with the load, the control electrode of each element being excited by at least part of the input signal, e.g. so-called totem-pole amplifiers with MOSFET's
