摘要: 本文研究了高、低电平输出偏置条件下双极电压比较器LM311的电离总剂量(Total Ionizing Dose,TID)—单粒子瞬态(Single Event Transient,SET)的协同效应.实验结果表明,高电平输出偏置条件下累积总剂量后的LM311的SET会受到明显抑制,主要表现为瞬态脉冲宽度减小,SET幅值变小.低电平输出偏置条件下累积总剂量后的LM311的SET有促进作用,主要表现为瞬态脉冲宽度增大,SET幅值变大.与高电平输出偏置条件相比,LM311在低电平输出偏置条件下对SET不敏感.发现TID诱发的界面态陷阱电荷和氧化物陷阱电荷是TID-SET协同抑制效应出现的根本原因.

Abstract: This paper investigates the synergistic effect of Total Ionizing Dose (TID) -Single Event Transient (SET) of the bipolar voltage comparator LM311 under high and low level output bias conditions. The results showed that the SET of LM311 after the cumulative total dose under high level output bias condition was significantly inhibited, mainly due to the decrease of transient pulse width, and the SET amplitude was also slightly reduced. The SET of LM311 after accumulating the total dose under the condition of low-level output bias has a promoting effect, which mainly manifests as the transient pulse width increases and the SET amplitude increases. Compared with the high-level output bias condition, the LM311 is not sensitive to SET under the low-level output bias condition. It was found that the interface trap charges and oxide trap charges induced by TID are the root cause of the TID-SET synergistic inhibitory effect.

Key words: total ionization dose, single-particle transient, synergistic effect, bipolar voltage comparator
