摘要: 随着集成电路中工艺尺寸的不断缩减,锁存器也越来越容易受到粒子辐射引起的三节点翻转的影响。针对该问题,基于C单元的结构,提出一种低功耗、低延时和高鲁棒性的三节点翻转并自恢复的MKEEP锁存器。通过仿真实验和PVT的波动实验表明,相对于其他拥有三节点容忍或自恢复能力的锁存器,该锁存器拥有低功耗、低延迟和更小的面积开销,且对工艺、电压和温度的敏感度较低,优势明显。

Abstract: With the persistent reduction of process size in integrated circuits, latches are also more and more vulnerable to the influence of triple-node-upset caused by particles radiation. Aiming at this problem, a triple-node-upset tolerance and self-recovery MKEEP latch based on C-element with low power consumption, low delay and high robustness is proposed. Simulation experiments and PVT fluctuation experiments show that, compared with other latches with triple-node-upset tolerance or self- recovery capability, the proposed latch has lower power consumption, low delay and area overhead. At the same time, this latch is less sensitive to process, voltage and temperature, and has obvious advan- tages than referenced latches.

Key words: particles radiation, triple-node-upset, latch, self-recovery
