DIFFERENTIAL OPERATIONAL AMPLIFIER WITH PARAPHASE OUTPUT Russian patent published in 2012 - IPC H03F3/34 H03F3/45 

FIELD: electricity.

SUBSTANCE: differential operational amplifier with paraphase output comprises an input differential cascade, the first and second current mirrors, the first current-stabilising dipole, the first and second current-stabilising load dipoles, an additional transistor, the first and second feedback resistors, the first and second additional buffer amplifiers.

EFFECT: development of conditions, under which the output static cophased voltage of the DA will have high stability and value close to zero.
