A 3- mu m CMOS timing sampler is described which is designed to be flown on the Combined Release and Radiation Effects Satellite. It consists of 64 inverter-pair stages with sampling latches and decoder circuitry, and is used to measure inverter-pair propagation delays, which are nominally 2.5 ns, with a resolution of 100 ps. A simple model was developed to explain the radiation-induced inverter-pair delay shifts in terms of radiation-induced MOSFET threshold-voltage shifts and effective nodal capacitances. The magnitude of the shift in pair delay with radiation was estimated at the point where the n-MOSFET threshold voltage became zero. For a 0.7-V threshold shift, the pair delay increased from its preradiation value by 360 ps for a rising step input and decreased by 190 ps for a falling step input, 1987 Annual Conference on Nuclear and Space Radiation Effects, 28-31 July 1987, Snowmass Village, CO, USA
