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

FIELD: radio electronics.

SUBSTANCE: operational amplifier is proposed, the circuit of which includes the first (16), second (17), third (18) and fourth (19) additional transistors, the first (20) additional current-stabilizing two-terminal network, the second (21) additional current-stabilizing two-terminal network, the third (22) additional current-stabilizing two-terminal network, the fourth (23) additional current-stabilizing two-terminal network, and the emitter of the first (16) additional transistor is connected to the emitter of the fourth (19) additional transistor through the first (24) additional correction capacitor, the emitter of the second (17) additional transistor is connected to the emitter the third (18) additional transistor through the second (25) additional correction capacitor, and the collectors of the third (18) and fourth (19) additional transistors are connected to the input of the buffer amplifier (12).

EFFECT: providing higher levels of output current in the structure of the intermediate stage of the operational amplifier, which recharges the integrating correction capacitor of the op-amp during the front of the transient process.
