FIELD: radio engineering.
SUBSTANCE: differential operational amplifier with a paraphrase output comprises the first and second input transistors, from the first to the fourth current-stabilising dipoles, the first and second current mirrors, the first and second additional transistors, the first and second additional resistors.
EFFECT: development of conditions, under which the output static cophased voltage of the DA will have high stability and value close to zero.
