Abstract

This article proposes a robust and low power flip-flop cell with complete double-node-upset (DNU) tolerance for aerospace applications. The proposed cell is constructed from a master latch and a slave latch. The master latch comprises two C-elements as well as one clock-controlled C-element; the slave latch is similar to the master but has an extra keeper to avoid high-impedance state of the output-level C-element. The proposed cell can provide complete DNU-tolerance while reducing power dissipation by 65x0025; on average when compared with existing radiation-hardened flip-flop cells.

一种高鲁棒性和低功耗的触发器单元，具有完全的双节点破坏公差，用于航空航天应用

本文提出了一种适用于航空航天应用的具有完全双节点镦粗（DNU）容限的鲁棒低功耗触发器单元。所提出的单元由主锁存器和从锁存器构成。主锁存器包括两个C元件以及一个时钟控制的C元件；从锁存器类似于主锁存器，但是具有额外的保持器以避免输出电平C元件的高阻抗状态。所提出的电池可以提供完全的DNU容限，同时将功耗降低65x0025；当与现有的辐射硬化的触发器单元相比时，平均而言。
