OPERATING AMPLIFIER Russian patent published in 2013 - IPC H03F3/34 

FIELD: radio engineering.

SUBSTANCE: operating amplifier includes first (1) and second (2) input transistors, non-inverting input (3) of the device, first (4) and second (5) forward-biased p-n junctions, inverting (6) input of the device, first (7) current-stabilising bipole, first (8) bus of power supply, second (9) current-stabilising bipole, second (10) bus of power supply, first (11) output transistor, first (12) auxiliary supply voltage source, third (13) current-stabilising bipole, second (14) output transistor, second (15) auxiliary supply voltage source, fourth (16) current-stabilising bipole, third (17) and fourth (18) input transistors.

EFFECT: reduction of input static current of operating amplifier, increase in quick action of operating amplifier at impulse input signals.
