Radiation-Hardened Voltage Comparators for the Synthesis of Microcircuits on the Array Chip MH2XA030

A brief information on the bipolar field-effect (BiJFET) array chip (AC) MH2XA030, designed to create radiation-hardened and cryogenic analog integrated circuits (ICs) for processing sensor signals, is presented. The features of the radiation-induced alterations in the parameters of bipolar transistors (BJTs), which must be taken into account when designing analog ICs on the AC, are considered. The electric circuits of the developed voltage comparators (VCs), which differ in fast response and power consumption, as well as the simulation results of their static and dynamic parameters on exposure to gamma emission and neutron flux, are presented. The designed VCs can find their application in the devices for space tool engineering and nuclear electronics.
