Development of Measurement System for Radiation Effect on A/D Converter

A measurement system for radiation effects on analogtodigital (A/D) converter based on histogram method was developed. Testing principle, system composition, control flow and systemic function were described. Total dose effects experiment of 12 bit AD574AJD using the system was carried out on 60Co source to verify its effectivity. The results show that the static parameters and functional parameters gained by the system can accurately reflect the damage effect of the devices under test. So the system is a well test bench for radiation effects on A/D converter.
