The radiation-hardened BiJFet differential amplifiers with negative current feedback on the common-mode signal

The article considers the advanced two-stage architectures of the differential op-amps and differential difference operational amplifiers, realized on the base BiJFet of array chips AGAMC1.3, AGAMC2.1 (OJSC “Integral”, Minsk). The suggested circuits provide the higher voltage gain (more than 90...100 dB), and also the low offset voltage (less than 100 μV) over the temperature range -80°C - +80°C, the neutron flux up to 1013 n/cm2, and the accumulated dose of radiation up to 3 Mrad. The mathematical justification of the main parameters is given. The results of their computer simulation are presented.
