FIELD: radio electronics.
SUBSTANCE: first (20) additional transistor is introduced into the high-speed operational amplifier circuit, the emitter of which is connected to the first (4) power supply bus through the first (21) additional current-stabilizing two-terminal network and is connected to the base of the first (6) intermediate stage transistor through the first (22) additional correction capacitor, the collector is matched to the second (7) power supply bus, the second (23) additional transistor, the base of which is connected to the second (2) input, the emitter is connected to the first (4) power supply bus through the second (24) additional current-stabilizing two-terminal network and is connected to the base of the second (12) transistor of the intermediate stage through the second (25) additional correction capacitor, the collector of the second (23) additional transistor is matched to the second (7) power supply bus.
EFFECT: increase in the maximum rate of rise of the output voltage of the negative edge of the transient process in the operational amplifier.
