Evaluation of a design methodology dedicated to dose-rate-hardened linear integrated circuits

A design methodology to harden linear integrated circuits with respect to high dose-rate effects is presented. It takes into account the photocurrents induced within the substrate which are responsible for the major degradation of the electrical response of the circuits. This noninvasive approach can be applied to any electronic function. Laser irradiation is used to validate the technique, so that very high levels of dose rates can be experimentally simulated.
