FIELD: radio engineering and communications.
SUBSTANCE: invention relates to the field of radio engineering and communications and can be used as a device to amplify analog signals. Differential amplifier for complementary field-effect transistors with controlled voltage limiting the pass-through characteristic contains first (1) input of the input field-effect transistor (2), second (3) input of the input field-effect transistor (4), first (5) current output, first (6) power supply bus, second (7) current output, first (8) auxiliary field effect transistor, third (9) current output, second (10) power supply line, second (11) auxiliary field effect transistor, fourth (12) current output, and the channels of first (2) and second (4) input field-effect transistors have the first type of conductivity, and the channels of first (8) and second (11) auxiliary field-effect transistors have a different type of conductivity. Differential amplifier also includes first (13), second (14), third (15), fourth (16), and fifth (17) additional resistors.
EFFECT: technical result is to increase the stability of the static mode at negative temperatures and changes in the supply voltage, it also provides the ability to change the numerical values of the voltage limit of the pass characteristics at a fixed current consumption.
