DIFFERENTIAL OPERATION AMPLIFIER Russian patent published in 2017 - IPC H03F3/45 

FIELD: radio engineering, communication.

SUBSTANCE: first (14) and the second (15) and the third (16) and the fourth (17) additional output transistors are entered into the scheme, the emitters of which are connected to the second 6 power source busbar, the bases of the first (14) and the second (15) additional output transistors are connected to the base of the first (10) output transistor, the base of the third (16) and the fourth (17) additional output transistors are connected to the base of the second (12) output transistor, the collectors of the first (14) and the third (16) additional output transistors are connected to the first (5) current output of the input differential stage (1), the collectors of the second (15) and the fourth (17) additional output transistors are connected to the second (8) current output of the intput differential stage (1). As a first (7) and second (9) matching two-poles used current-stadilized two-pole high internal resistance.

EFFECT: increasing voltage gain in the open differential operation amplifier with a high thermal and radiation stability of the transistor static mode at its intermediate stage.
