Quantum-dot Cellular Automata (QCA) technology is attractive due to its low power consumption, fast speed and small dimension; therefore it is a promising alternative to CMOS technology. Additionally, multiplexer is a useful part in many important circuits. In this paper we propose a novel design of 2:1 MUX in QCA. Moreover, a 4:1 multiplexer, an XOR gate(More)
—Although the trend of technology scaling is sought to realize higher performance computer systems, it also results in Integrated Circuits (ICs) suffering from increasing Process, Voltage, and Temperature (PVT) variations and adverse aging effects. In most cases, these reliability threats manifest themselves as timing errors on critical speed-paths of the(More)
Nanotechnologies, notably Quantum-dot Cellular Automata (QCA), provide an attractive perspective for future computing technologies. In this paper, Quantum-dot Cellular Automata (QCA) is investigated as an implementation method for reversible logic. A novel XOR gate and also a new approach to implement 2:1 multiplexer are presented. Moreover, an efficient(More)
Quantum-dot cellular automata (QCA) is a transistor-less computation approach which encodes binary information via configuration of charges among quantum dots. The fundamental QCA logic primitives are the majority gate and the inverter gate which can be employed to design various QCA circuits. In this study by applying some fixed predefined level of(More)
—As the number of on-chip processor cores increases, power-efficient solutions are sought for data communication between cores. The Helix-h non-blocking photonic switch is developed to improve physical-layer and network performance parameters for a wide range of silicon nano-photonic multicore interconnection topologies. Traffic benchmarks and practical(More)
