摘　　要：利用变温辐照方法模拟了低剂量率辐照,研究了双极电压比较器LM2903的电离总剂量(TID)-单粒子瞬态(SET)的协同效应。结果表明,高电平工作状态偏置时,TID对LM2903的SET具有抑制作用;低电平工作状态偏置时,TID对LM2903的SET具有促进作用。电离辐照诱发的界面态缺陷电荷是TID-SET协同效应产生的根本原因,电压比较器的输出级结构导致了偏置状态对TID-SET协同效应的不同影响。The synergistic effect of total ionizing dose(TID)and single event transient(SET)in bipolar voltage comparator LM2903 was studied by temperature switching irradiation method which can simulate low-dose-rate irradiation.The result shows that TID has a suppressing effect on the SET of LM2903 at the high-level working state for bias voltage,and TID can promote the SET of LM2903 at the low-level working state for bias voltage.The interface state defect charge induced by ionizing irradiation is the fundamental cause of the synergistic effect of TID-SET.The output stage structure of voltage comparator causes different effects of the bias state on the synergistic effect of TID-SET.
