摘要

Internal SET has become a great concern in normal radiation-hardened flip-flops with increases in frequency. We investigate the internal SET problem in the traditional hardened flip-flops in this article. We also propose a novel structure to eliminate the internal SET problem. Three-dimensional technology computer-aided design (TCAD) was adopted to verify the hardened performance of this proposed novel structure. Besides, the power and setup time were compared with the traditional hardened flip-flops.
