双极晶体管瞬态辐射光电流分流补偿法及其实验研究

A photocurrent compensation method of bipolar transistors under high dose rate radiation and its experimental research

采用标准分立双极元件,对双极晶体管瞬态辐射光电流分流补偿法进行了实验验证。给出了双极晶体管瞬态辐射响应及光电流分流补偿原理,比较了带补偿与不带补偿电路的瞬态响应波形。实验结果对双极晶体管集成电路瞬态辐射加固具有指导意义。

Experiment using discrete bipolar transistors has been performed to verify the effect of the photocurrent compensation method. The theory of the dose rate effects of bipolar transistors and the photocurrent compensation method are introduced. The comparison between the response of hardened and unhardened circuits under high dose rate radiation is discussed. The experimental results show instructive ness to the hardness of bipolar integrated circuits under transient radiation.
