Abstract
CMOS circuit hardness to total ionizing dose is improved by a circuit techn ique that dynamically adjusts well and/or substrate;voltages to maintain co nstant device threshold voltages. Threshold voltage excursions below a refe rence value activate an oscillator driving a charge pump. Stabilization is demonstrated experimentally. Techniques for optimizing the circuitry for va rious CMOS technology implementations are provided and supported with simul ations.
