<p>The invention relates to a push-pull amplifier, comprising an input (12) and an output (14), which includes: a main amplification branch comprising two amplification transistors (18, 20) connected in opposite series between two supply voltages (V+, V−), the amplifier output (14) being connected between the two transistors (18, 20), and a control circuit (22, 24) for each amplification transistor (18, 20) connected to the input (12) to each receive as an input the signal to be amplified. The main amplification branch comprises, between each transistor (18, 20) and the output (14), a member having a nonlinear response (38, 40) and means (30, 32) for introducing at the input of the control circuit (22, 24) of each transistor (18, 20), a nonlinear compensating signal suitable for bringing about the circulation of a minimum current in the member having a nonlinear response (38, 40).</p> |
