HIGH-SPEED DIFFERENTIAL OPERATIONAL AMPLIFIER WITH DIFFERENTIATING CORRECTION CIRCUITS Russian patent published in 2019 - IPC H03F3/45 

FIELD: electrical engineering.

SUBSTANCE: invention relates to differential operational amplifiers. Differential operational amplifier comprises an input differential cascade with differential inputs, as well as first and second current outputs, first and second output transistors, the combined bases of which are connected to a bias voltage source, a first current-stabilizing dipole, a second current-stabilizing dipole, a first resistor of a collector load, a second resistor of a collector load, a current output of the device, first and second auxiliary transistors, first current-stabilizing two-terminal device and first correcting capacitor, first additional current mirror, third auxiliary transistor, a fourth auxiliary transistor, a second current-stabilizing dipole and a second correcting capacitor, a second current mirror and a third correcting capacitor.

EFFECT: technical result consists in increase of maximum rate of increase of output voltage without deterioration of energy parameters.
