FIELD: radio engineering, communication.
SUBSTANCE: complementary differential amplifier with an expanded active operation range comprises a first (1) and a second (2) input transistor, inputs (3), (4) of the device, a first (5) and a second (6) output transistor, a reference current source (7), a first (8) and a second (9) current-limiting resistor, first (10) and second (11) series-connected auxiliary resistors, an auxiliary forward-biased p-n junction (12), a common node (13), a first group of antiphase current outputs (14, 15), a second group of antiphase current outputs (16, 17), an emitter p-n junction of an additional transistor (18), a power supply bus (19).
EFFECT: wider active operation range of the input stage of the operational amplifier for a differential signal and obtaining limiting voltage values of the transfer characteristic thereof.
