Scientific paper

Radiation-hardened A/D converters suitable for converting the output of FPA signals in an SDI environment have not been readily available. Hughes developed a 10-bit, 1-MSPS, total-dose and dose-rate hard A/D converter using a proprietary radiation-hardened bulk CMOS process. This paper describes the A/D converter architecture, semiconductor process, and circuit design. Test results show over 1-Mrad(Si) total-dose tolerance and up to 7 x 10 exp 11 rad(Si)/s at 125 C dose rate without latchup. Neutron fluences up to 3 x 10 exp 14 neutrons/sq cm show negligible effects.
