NMOS大气中子辐射效应仿真研究
|
摘要
在临近空间内运行的临近空间飞行器,容易受到临近空间中大气中子的辐射影响,尤其是其上搭载的FPGA等大规模集成电路,极易发生单粒子翻转,影响整个飞行器的安全运行。单粒子翻转大多由于NMOS管受粒子辐射作用产生瞬态脉冲电流导致,论文利用TCAD对NMOS管进行建模,仿真得出受不同能量中子辐射所产生的脉冲电流,从而找到利用仿真手段得出NMOS管受大气中子辐射影响产生瞬态电流的方法,为后续研究FPGA受大气中子辐射单粒子效应奠定基础。
The spacecraft running in the space is susceptible to the influence of atmospheric neutron radiation in the nearspace,especially the large-scale integrated circuits such as FPGAs,which can easily flip single particles and affect the safe opera-tion of the whole aircraft. In this paper,the NMOS tube is modeled by TCAD,and the pulse current generated by different energyneutron radiation is simulated to find out that the NMOS transistor is used to generate the pulse current. The method of NMOS tube isfound by atmospheric neutron radiation to produce transient current for the follow-up study of atmospheric neutron radiation by atmo-spheric neutron radiation.
