For digital circuit/system architectures, the triple modular redundancy (TMR) scheme is widely used to cope with circuit/system faults. The TMR scheme involves duplication of a circuit/system twice and the majority voter, based on Boolean majority logic, ensures that the architecture remains functional even if any copy of circuit/system may become faulty at any time. However, the fundamental as...

A Triple-modular redundancy (TMR) system will have a failure if Single Event Transient (SET) faults affect the voter. In this paper, we propose a full SET-tolerance dual-modular majority voter (DMV) circuit for all internal nodes. The DMV consisting of two simplex-modular voters, two inverters, a C-element inverter and a weak keeper is implemented in CMOS 40 nm technology. A novel XOR gate and ...

Defect rate in Nanoelectronics is much higher than conventional CMOS circuits. Hardware redundancy can be a suitable solution for fault tolerance in nano level. A voter circuit is a part of a redundancy based fault tolerant system that enables a system to continue operating properly in the event of one or more faults within its components. Robustness of the voter circuit defines the reliability...
