Efficient design and simulation of novel exclusive-OR gate based on nanoelectronics using quantum-dot cellular automata

Abstract

QCA is a modern transistor-less computational paradigm in nanotechnology, which encodes digital binary information via configuration of charges among quantum dots. The nanostructure’s “Quantum dots” is a liberal of promises nanotechnology for implementation of digital mode on the nanoscale in nanometer (nm), based on cells of coupled quantum dots. It is a highly intensifying nanotechnology that has very fast switching speed and power consumption extremely low as compared to transistor technique. We have implemented the novel Exclusive-OR gate using QCA technology, with designs having significant improvement in layout of quantum cell used area, latency, and power as compared to past idea. The proposed novel XOR layout based on quantum-dot cell used only 17 cells, 0.03 μm2, and latency of 0.25 clock cycles. These layouts are designed and simulated by QCA designer Version-2.0.3 tool, by taking unique features and many advantages of the nanotechnology; the complete layout circuits design on a single layer of QCA.
