摘要: Using the technology computer-aided design three-dimensional simulation, the supply voltage scaled dependency of the recovery of single event upset and charge collection in static random-access memory cells are investigated. It reveals that the recovery linear energy transfer threshold decreases with the supply voltage reducing, which is quite attractive to the dynamic voltage scaling and subthreshold circuits radiation-hardened design. Additionally, the effect of supply voltage on charge collection is also investigated. It is concluded that the supply voltage mainly affects the bipolar gain of parasitical bipolar junction transistor (BJT) and the existence of the source plays an important role in the supply voltage variation.

关键词: single event upset, multi-node charge collection, recovery, ultra-low ower voltage
