HIGH-SPEED OPERATIONAL AMPLIFIER WITH DIFFERENTIATION CIRCUIT OF CORRECTION Russian patent published in 2018 - IPC H03F3/45 

FIELD: radio equipment; electronics.

SUBSTANCE: invention relates to the field of radio engineering and analog microelectronics and can be used in various analog and analog-digital interfaces for the processing of sensor signals. High-speed operational amplifier contains the first and second input transistors, a power source, a current-stabilizing two-terminal network, the first correction capacitor associated with the collector of the first input transistor, the current mirror matched to the second power supply bus, the buffer amplifier.

EFFECT: technical result consists in increasing the maximum rate of increase in the output voltage and reducing the time for establishing the transient process in the op amp.
