Abstract
This paper presents a gamma radiation dosimeter built in a standard 0.35 mum CMOS technology. The dosimeter, which occupies 300 times 150 mum times mum of silicon area, gives a digital output signal of frequency proportional to the total dose. Experimental results up to 1.5 Mrads are presented. Measured low dose radiation responsivity is 84.7 Hz/Krad and sensitivity to temperature and supply voltage are 1.43 kHz/degC and 20.9 kHz/V, respectively.
