Abstract

For operability of silicon analog integrated circuits with influence of penetrating radiation and low temperatures designed constructions: double gate JFET, high-ohmic semiconductor resistor for operating in temperatures below minus 100 0Ñ, BiJFET Array Chip and new circuits of operational amplifier with inbuilt common-mode signal feedback, multidifferencial operational amplifier with input JFET, charge-sensitive amplifier with input double gate JFET. Results of volt-ampere characteristic experimental measurements of integral elements are shown and special features of SPICE-models are considered. Electric circuits of microelectronic analog devices are described, their modeling results are analyzed and main advantages are highlighted. So, operational amplifier provide low value of input offset voltage, operability with influence of penetrating radiation (experimentally confirmed save of operability with influence of fast electron fluence up to 3,7×1014 el/cm2 with energy of 6 MeV) and possibility of electronic shift of constant output voltage level. Multidifferencial operational amplifier hold gain above 90 dB with temperature minus 197 0Ñ or neutron fluence of 1015 n/cm2. Using double gate JFET in charge-sensitive amplifier circuit allowed improve its parameters for signal sources with low internal capacity substantially. So, with the internal capacitance of the signal source about 1 pF equivalent noise charge is reduced by 2,15 times, and output rise time is reduced by 9,47 times.
