Linear system theory techniques were used to predict threshold-voltage shifts for 4007 inverters at dose rates of 270, 49.7, and 0.19 rad(Si)/s, from a transient annealing curve determined following a 5-rad(Si)/s 60.Co irradiation. These predictions were compared with threshold-voltage shifts obtained following 60.Co irradiations actually performed at these dose rates, and the agreement is excellent. We observed a wide range of annealing rates for commercial and military 4007 inverters - some Al-gate inverters exhibited very little annealing following iradiation, while an Si-gate inverter completely annealed back to its preirradiation threshold voltage.
