This paper presents a novel design of quaternary logic gates using graphene nanoribbon field effect transistors (GNRFETs). GNRFETs are the alternative devices for digital circuit design due to their superior carrier-transport properties and potential for large-scale processing. In addition, Multiple-valued logic (MVL) is a promising alternative to the conventional binary logic design. Sa...

This paper investigates a novel design of penternary logic gates usingcarbon nanotube field effect transistors (CNTFETs). CNTFET is a suitable candidate forreplacing MOSFET with some useful properties, such as the capability of having thedesired threshold voltage by regulating the diameter of the nanotubes. Multiple-valuedlogic (MVL) such as ternary, quaternary, and penternary is a promising al...

all practical digital circuits are usually a mixture of combinational and sequential logic. flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. the concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...

the design and application of a fuzzy logic based controller to a leakage current relay waspresented in this paper. a novel approach based on fuzzy logic to form the tripping action of leakagecurrent relay was investigated. in addition to the theoretical aspect of fuzzy logic, detection of a leakagecurrent, measurement of the leakage current, determination of its duration, trip opening of fault...
