RADIATION HARDNESS ENSURING OF ANALOG INTEGRATED CIRCUITS

Abstract

Influence of gamma radiation Co60 on static and dynamic characteristics of the transresistance amplifier and the comparator realized on the master slice array «ABMK 1-3» is considered taking into account formulated design rule. At absorbed dose D = 5 Mrad the comparator input current has increased on 25 %, other IC parameters (gain, impulse response of the transresistance amplifier, propagation delay, transition time, output current of the comparator) have changed slightly.
