Parameter variation and susceptibility of soft errors in nanometer process technologies pose a major design challenge for high performance IC designs. Most circuit design solutions to the nanometer process related errors rely on space and time redundancy technologies. The existing solutions to the distributed memory components such as latch, flip flop, and registers suffer from large area overhead while providing relatively less reliability protections. In this paper, we propose a new flip flop adapting the c-elements and time delay filtering. The proposed flip flop is robust to both PVT variation and soft error. Also the proposed circuit provides both error detection and correction while improving circuit performances such as WOV and correction cycle with little area overhead compared to the existing approaches.
