FIELD: radio engineering; analogue microelectronics.
SUBSTANCE: input stage of the differential operational amplifier includes power supply sources, output field-effect transistors, a current-stabilizing dipole, additional field-effect transistors, as all the above field-effect transistors, field-effect transistors with a control p-n junction are used.
EFFECT: technical result consists in providing operability of IS and OpAmp based on it in the range of cryogenic temperatures and exposure of penetrating radiation, as well as obtaining high values of differential gain.
