双极电压比较器不同条件下总剂量辐射效应

摘要

为分析电压比较器在空间辐射环境下的损伤变化规律,对电压比较器在不同偏置和剂量率下的电离辐射效应进行了系统研究.结果表明,电压比较器的多个参数均发生较大变化,且敏感参数与辐照条件有很强的依赖关系.不同偏置的高低剂量率辐照结果显示,比较器的剂量率效应与偏置相关,不同偏置条件下,器件的辐射损伤模式略有不同.%The bipolar voltage comparators with different biases were irradiated at high and low dose rates to investigate their total dose effect. The results show that many electrical parameters change and the sensitive parameters vary with the biases. Through comparing the damage at high and low dose rates, it is found that the dose rate effects depended on the biases and the damage model changes with the biases.
