摘要
讨论了CMOS器件受辐射感生的闩锁与电气感生的闩锁的异同点,研究并提出了一种基于限流型低压降线性调整器的闩锁防护方法,给出了卫星用线性调整器电路的地面总剂量摸底试验数据及空间飞行试验验证结果和解决星载计算机的闩锁防护与恢复问题的有效方法.
This paper discusses the similarities and differences between the latch-up induced by electrics and the latch-up induced by radiation for CMOS IC's. A technical scheme for Latch-up protection based on current rejection by a low-dropout linear voltage regulator (LDO) is developed, with the onboard experimental result and the experimental data of TDO on ground of the LDO circuit used on the satellite given. Finally, the problem of protection and recovery from latch-up on the onboard-computer has been solved.
