Quantum and reversible logic circuits have more advantages than the common circuits, like low power consumption. These circuits are good choice to design future computers. One of the important issues in reversible logic is parity preservation. If parity of inputs and outputs are equal in reversible gate, this gate will be parity preserve. Reversible circuits made by these gates are parity prese...

quantum-dot cellular automata (qca) is an emerging and promising technology that provides significant improvements over cmos. recently qca has been advocated as an applicant for implementing reversible circuits. however qca, like other nanotechnologies, suffers from a high fault rate. the main purpose of this paper is to develop a fault tolerant model of qca circuits by redundancy in hardware a...

Fault-tolerant design of analog circuits is more difficult than that of digital circuits. Abhijit Chatterjee has proposed a continuous checksum-based technique to design fault-tolerant linear analog circuits. However, some faults in the passive elements cannot be detected if the checker has not been designed appropriately. This paper addresses the fault coverage issue in the continuous checksum...

Abstract: Error detectable and error correctable coding in Hamming space was researched to discover possible fault tolerant coding constellations, which can implement Boolean logic with fault tolerant property. Basic logic operators of the Boolean algebra were developed to apply fault tolerant coding in the logic circuits. It was shown that application of three-bit fault tolerant codes have pro...

We describe a method for designing fault tolerant circuits based on an extension of a Concurrent Error Detection (CED) technique. The proposed extension combines parity check codes and duplication in order to not only perform error detection but also provide diagnosis and correction capabilities. Informed selection among the outputs of the original synthesized circuit and the outputs of a const...
