In this paper, we propose some soft-error-tolerant latches and flip-flops that can be used in dual-VDD systems. By utilizing local redundancy and inner feedback techniques, the latches and flip-flops can recover from soft errors caused by cosmic rays and particle strikes. The proposed flip-flop can be used as a level shifter without the problems of static leakage and redundant switching activity. Implemented in a standard 0.18-µm technology, the proposed latches and flip-flops show superior performance compared to conventional ones in terms of delay and power while keeping the soft-error-tolerant characteristic. Experimental results show that compared to the traditional built-in soft-error-tolerant D latch, the D-QN delay of the new D latch is 29.1% less than that of the traditional built-in soft-error-tolerant D latch while consuming 16.5 % less power as well. The D-Q delay and power of the new flip-flop are about 47.7% and 54% less than those of the traditional high speed level-converting flip-flop, respectively. In addition, the proposed flip-flop is more robust to soft errors. The critical charge which represents the minimum charge at the D input required to cause an error of the flip-flop can be increased by more than 46.4 %. The time window during which the flip-flop will be erroneous caused by single-event upsets at the D input is reduced by more than 22.2%.
