Title: Multiple push-pull power amplifier - produces high output using LV transistors with series-coupled collector-emitter between supply
Inventor: ANSORGE WERNER
IPC: H03F1/02
Filed: 1972-04-13
Abstract: The multiple push-pull power amplifier has several interconnected push-pull transistor stages with the emitter/collector paths of their transistors connected in series between the two supply poles. The voltage requiring amplification also acts as a stage control signal. Transistors in one stage are turned off by a part of the collector/emitter voltage of the transistors in an earlier stage but turn on one after another as the control voltage increases. The advantage lies in using cheap, low voltage transistors to generate high output voltages. The control voltage is amplified to a high grade of fidelity.
