Push=pull output stage amplifier for analog signals

摘要

The amplifier comprises a voltage pre-amplifier (1,2), an output stage of two branches - each with a series-connection of an amplifier element (7,10) and a forward biassed diode (8, 9) - and a biassing resistor (6). The push-pull amplifier output forms the junction point of the diodes of both branches. A controlled current generator (5) and two inverters (3,4) are additionally incorporated. A first voltage pre-amplifier output is coupled to first amplifier element (10) control input, while its second output leads to the second amplifier element (7) control input. The two inverters are incorporated between the push-pull amplifier output and corresp. inputs of the current generator.
