Abstract

Radiation tolerance of CMOS circuits to total dose can be improved by adjusting the p-substrate voltage to keep the n-channel threshold voltage above a minimum value. This paper presents a circuit design, implemented on an IC and on a breadboard, for dynamically adjusting the substrate voltage. Experimental results clearly show that devices with threshold voltage stabilization exhibit longer lifetime as compared to those without the stabilization circuit.
