LOW-TEMPERATURE RADIATION-RESISTANT MULTIDIFFERENTIAL OPERATING AMPLIFIER Russian patent published in 2017 - IPC H03F3/45 

FIELD: electricity.

SUBSTANCE: low-temperature radiation-resistant multidifferential operational amplifier contains the first (1) differential cascade based on the first (2) and second (3) input transistors connected to each other by injecting bushings. The first (4) current output of the first (1) differential stage and the first (11) current output of the second (8) differential stage are connected to the input of the first (15) current mirror, the second (12) current output of the second (8) differential stage is connected to the output of the second (18) current mirror and is connected to the input of an additional inverting amplifier (20) matched to the second (19) power supply bus, the current output of which is connected to the current output of the device (17).

EFFECT: reduction of the systematic component of zero bias voltage, creation of conditions for application of the proposed transistors CMOS device in the circuit.
