Circuit Nanotechnology: QCA Adder Gate Layout Designs
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 2
Abstract
Quantum-dot Cellular Automata (QCA) based circuit designs have been explored since its concept development in early 1980’s. Although there are lot of implementation barriers for the development of this nanotechnology to work smoothly at room temperature but the simulated circuit implementations have attracted a large number of researchers towards this new field. The success of metal dot implementation even at very low temperatures has paved a way for exploring new possibilities in computing paradigm. An ample of circuit layouts have been proposed for the design of EX-OR gate, a vital element for arithmetic processes. We have analyzed some reported layouts in terms of their simulation accuracy, latency, cell count and noise performance to propose few single layer robust circuits for their efficient implementation
