Design of hardened flip-flop using Schmitt trigger-based SEM latch in CNTFET technology
Abstract
Purpose
The purpose of this paper is to design novel hardened flip-flop using carbon nanotube field effect transistors (CNTFETs).
Design/methodology/approach
To design the proposed flip-flop, the Schmitt trigger-based soft error masking and unhardened latches have been used. In the proposed design, the novel mechanism, i.e. hysteresis property is used to enhance the hardness of the single event upset.
Findings
To obtain the simulation results, all the proposed circuits are extensively simulated in Hewlett simulation program with integrated circuit emphasis software. Moreover, the results of the proposed latches are compared to the conventional latches to show performance improvements. It is noted that the proposed latch shows the performance improvements up to 25.8%, 51.2% and 17.8%, respectively, in terms of power consumption, area and power delay product compared to the conventional latches. Additionally, it is observed that the simulation result of the proposed flip-flop confirmed the correctness with its respective functions.
Originality/value
The novel hardened flip-flop utilizing ST based SEM latch is presented. This flip-flop is significantly improves the performance and reliability compared to the existing flip-flops.
