The analog array chip AC-1.3 for the tasks of tool engineering in conditions of cryogenic temperature, neutron flux and cumulative radiation dose effects

The array chip AC-1.3 (OJSC “Integral” Minsk, Belarus) is a base for construction of more than 20 integrated circuits (ICs) for the goals of tool engineering and diagnostics. The article presents the results obtained in experimental studies of the effects of low-temperatures (up to minus -190°C and radiation on the DC characteristics and the current gain (β) of n-p-n and p-n-p bipolar transistors and also JFETs, which contain AC-1.3 in their structure. The paper gives design recommendations for new semi custom microcircuits based on AC-1.3, operating in space conditions.
