对一款双极集成、三端线性稳压器LM317进行了不同偏置、不同剂量率条件下的电离辐射效应及室温退火特性研究。研究结果表明:器件输出电压、输入输出压差等敏感参数在电离辐射环境下发生了不同程度的变化,且在零偏偏置辐照下的变化比工作偏置辐照下的变化大;在零偏偏置条件,总剂量相同时低剂量率辐照下的损伤明显大于高剂量率辐照,表现出低剂量率损伤增强效应;在工作偏置条件,高剂量率辐照下的损伤大于低剂量率辐照下的损伤,但随后的退火实验中恢复到低剂量率辐照损伤水平,表现出时间相关效应。对稳压器辐射敏感参数的影响因素和不同偏置下的剂量率影响进行了分析和讨论。 |

The radiation responses and room-temperature annealing behaviors of linear voltage regulator LM317 with different bias are investigated in this paper. The results show that the key electrical parameters of the regulator, such as the 'output voltage' and the 'drop voltage' are sensitive to total ionizing radiation and dose rates. In the 'zero' bias condition, the damage at high dose rate is smaller than that at low dose rate, indicating obvious low dose rate sensitivity (ELDRS). While in the 'operating' bias condition, the damage at high dose rate is obviously greater than that at low dose rate and it recovers rapidly in following post-irradiation annealing, which shows obvious time dependent effects (TDE). Finally, the influencing factors of radiation sensitive parameters and dose rate influences under the different bias are analyzed and discussed. |
