摘要

随着集成电路技术的快速发展，锁存器对由电荷共享引起的多节点扰流（MNU）的敏感性显著提高，这一现象已成为影响纳米级集成电路可靠性的核心问题。本文提出了一种高稳定、高性能、低成本的四节点干扰容忍锁存器（DUAL-RDTL），该锁存器通过在输出阶段配置两个DNU恢复锁存器（RDTL）和三个c元来实现完全的QNU容忍。在22 nm PTM技术下的HSPICE仿真结果表明，与现有的辐射硬化锁存器（QNUTL、SEI-QNUTL、4NUHL）相比，DUAL-RDTL的功耗平均降低44.69%，延迟平均降低7.09%，功率延迟平均降低49.01%，同时对PVT （Process, Voltage, Temperature, Process, Voltage, Temperature）变化表现出最佳的稳定性。

A QNU hardened latch design with low cost high stability and high performance

With the rapid development of integrated circuit technology, the sensitivity of latches to Multiple Node Upsets (MNU) induced by charge sharing has significantly increased, and this phenomenon has become a core issue affecting reliability in nanoscale integrated circuits. This paper proposes a high stability, high-performance, low-cost quadruple-node-upset (QNU) tolerant latch (DUAL-RDTL), which achieves complete QNU tolerance through the configuration of two DNU recovery latches (RDTL) and three C-elements at the output stage. HSPICE simulation results under 22 nm PTM technology demonstrate that compared with existing radiation hardened latches (QNUTL, SEI-QNUTL, 4NUHL), the DUAL-RDTL achieves average reductions of 44.69 % in power consumption, 7.09 % in delay, and 49.01 % in Power-Delay Product (PDP), while exhibiting the best stability against PVT (Process, Voltage, Temperature) variations.
