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

FIELD: radio engineering.

SUBSTANCE: amplifier with a paraphase output has input transistors (1, 2), output transistors (3, 4, 10, 12), a current mirror (5), power supply buses (6, 8), current stabilising two-terminal devices (7, 9, 11, 18, 19), feedback resistors (13, 16), an auxiliary differential amplifier (15), a reference voltage source (20), device outputs (14, 17). The current output of the auxiliary differential amplifier (15) is connected to collectors of the first (1) and the second (2) input transistors, wherein the first input of the auxiliary differential amplifier (15) does not invert the signal phase, and the second input of the auxiliary differential amplifier (15) inverts the phase of the input signal.

EFFECT: high stability of output static in-phase voltage of a differential amplifier.
