Total ionizing dose effects on voltage-to-frequency converters

Three different voltage-to-frequency converters were tested to determine how ionizing radiation affected their critical specifications. All three were fabricated with bipolar technologies. A popular charge-balancing architecture converter, AD652, was most sensitive with low dose rate (LDR) due to its tight specifications. The other astable-multivibrator architecture converters, AD537 and AD654, performed much better at high dose rate and low dose rate.
