HIGH-SPEED OPERATIONAL AMPLIFIER BASED ON COMPLEMENTARY BENT CASCADE Russian patent published in 2024 - IPC H03F3/34 

FIELD: radio electronics.

SUBSTANCE: operational amplifier is proposed, the circuit of which includes the first (23) and second (24) additional transistors, the first (25) additional current-stabilizing two-terminal network, the first (26) additional correction capacitor, the second (27) additional current-stabilizing two-terminal network, the second (28) additional correction capacitor, and the base of the second (24) additional transistor is connected to the emitter of the third (16) output transistor, the collectors of the first (23) and second (24) additional transistors are connected to the input of the buffer amplifier (19), and the collectors of the first (12) and the third (16) output transistors are connected to the common bus of the first (4) and second (8) power supplies.

EFFECT: during the front of the transient process, ensuring higher levels of the output current of the push-pull complementary bent cascade, which recharges the integrating correction capacitor of the op-amp.
