摘要: The radiation effects on several properties (reference voltage, digital output logic voltage, and supply current) of dual 8-bit analog-to-digital (A/D) converters (AD9058) under various biased conditions are investigated in this paper. Gamma ray and 10-MeV proton irradiation are selected for a detailed evaluation and comparison. Based on the measurement results induced by the gamma ray with various dose rates, the devices exhibit enhanced low dose rate sensitivity (ELDRS) under zero and working bias conditions. Meanwhile, it is obvious that the ELDRS is more severe under the working bias condition than under the zero bias condition. The degradation of AD9058 does not display obvious ELDRS during 10-MeV proton irradiation with the selected flux.

关键词: analog-to-digital converters, enhanced low dose rate sensitivities (ELDRS), gamma ray and proton irradiation, lower/high-dose rate
