Abstract

The electronic push-pull amplifier includes an output stage comprising two complementary transistors (T1, T2) connected by their collectors. Each emitter is connected directly to a supply terminal, and each base is connected to the corresponding omitter via a resistance. A control stage comprises two transistors (T3, T4) linked to the bases of the output transistors. Their bases receive the input signal. A feedback circuit includes a resistance (R1) linking points A and B, and resistance R2 and capacitance C2. Diodes (D1-2) determine the operating point of the final stage and the bias of the output transistors.
