DIFFERENTIAL OPERATIONAL AMPLIFIER WITH PARAPHASE OUTPUT Russian patent published in 2012 - IPC H03F3/45 

FIELD: radio engineering.

SUBSTANCE: differential operational amplifier with a paraphrase output comprises an input differential cascade, the first and second output transistors, from the first to the third current-stabilising dipoles, the first and second dipoles of a collector load, from the first to the fourth additional transistors, the first and second feedback resistors.

EFFECT: development of conditions, at which the output static cophased voltage of the differential amplifier will have high stability and zero value.
