FIELD: radio engineering, communication.
SUBSTANCE: in the amplifier, the circuit includes an additional p-n junction (17) between the emitter of the transistor of the reference current source (5) and the common bus (18) of the first (7) and second (10) power supplies, wherein the first (14) auxiliary output of the device is connected to the base of the transistor of the reference current source (5) through a first (19) feedback resistor, and the second (16) auxiliary output of the device is connected to the base of the transistor of the reference current source (5) through a second (20) feedback resistor.
EFFECT: high stability of output static in-phase voltage of the differential amplifier.
