LOW TEMPERATURE RADIATION RESISTANT MULTIDIFFERENCIAL OPERATION AMPLIFIER Russian patent published in 2017 - IPC H03F3/45 

FIELD: radio engineering, communication.

SUBSTANCE: multidifferencial operation amplifier (MOA) contains differential cascades, based on the transistors, connected to one another. The first (1) differential cascade current output is connected to the first power supply bus (15) through the first current stabilizing two-terminal circuit (18) and is connected to the emitter of the first matching transistor (19), the second current output (12) of the second differential cascade (8) is connected to the emitter of the second matching transistor (20) and through the second current stabilizing two-terminal circuit (21) it is connected to the first power supply bus (15). At that the first current output (11) of the second differential cascade (8) is connected to the emitter of the second output transistor (26), and it is connected to the manifold of the first matching transistor (19), the collector of the second output transistor (26) is connected to the second input (28) of the output differential cascade (25), which output is connected to the device output (17).

EFFECT: improvement of the accuracy by reducing the bias voltage systematic component of the zero low temperature radiation-resistant multidifferencial operational amplifier.
