PRECISION OPERATIONAL AMPLIFIER Russian patent published in 2012 - IPC H03F3/45

Abstract RU 2450425 C1

FIELD: radio engineering.

SUBSTANCE: precision operational amplifier comprises an input differential cascade, a current mirror, an output transistor, the first and second circuits of potential matching, a current-stabilising dipole, from the first to the fourth additional transistors, an additional p-n transition.

EFFECT: reduced absolute value of UCM and its temperature drift, higher amplification ratio for low-resistance loads.
