Abstract: The quantum-dot cellular automata (QCA) technology is a promising alternative technology to CMOS technology to extend the exponential Moore’s law progress of microelectronics at nanoscale level, which is expected to be beneficial for digital circuits. Quantum dot Cellular Automata are future representations of quantum reckoning, which is developed in resemblance to the predictable models of cellular automata familiarized by Von Neumann. Multiplexer is an important building block of digital circuits and very useful part in most frequently used logical circuits. The previous study of multiplexer designs simulates the basic elements or Combinational circuit. The results demonstrate that the previous QCA multiplexer architectures have the best performance in terms of clock delay, circuit complexity, and area in comparison with older QCA multiplexer architectures, day by day improvement reflected in the reechoes there is very tuff to analysis for new approaches to design new multiplexer circuits before we find few drawback in previous design and now we study most of the fine multiplexer design here. A 2:1 multiplexer has been designed and implemented before with the help of majority voters and successfully implemented in QCA. The MUX is more robust and enjoys single layer and single clock wire crossing, which requires only one type of cell .we try to design multiplexer circuit performs equally well compared to existing designs. We are study and try to design our own circuitry to overcome issue for this purpose we allow to choose different methodology and design techniques. QCADesigner software is used to create a detailed layout and for circuit simulation. The circuits simulated using QCADesigner. Keywords: Quantum Dot Cellular Automata, Nanotechnology, Multiplexer, QCADesigner-2.0.3.
I. INTRODUCTION Due to the dramatic increase rate in the number of transistors within the chip, reducing the size of transistors is essential, however in the CMOS technology, size reduction of transistors, at nano-scale, isn't always possible actually and the extension of Moore’s regulation in CMOS era past 10-nm isn't always possible as it introduces an anomalous quantum conduct in nanoscale .The quantum-dot cellular automata (QCA) technology is able to achieve higher speed and density and lower power consumption designs compared to conventional CMOS technology. The binary information in this technology is encoded by reconfiguration of the charges instead of current. So in recent years, circuit implementation in QCA technology has received a great deal of attention due to a number of promising applications such as efficient QCA full adder design [6–9], efficient QCA multiplier design [10,11], and efficient QCA multiplexer design. A John von Neumann, a Hungarian mathematician presented the idea of cell automata. The possibility of quantum calculation is by and large included to Feynman who proposed a computational model in view of quantum mechanical laws. The discrete idea of cell mechanization and quantum mechanics prompts the development of nanoscale circuits to perform calculation. One conceivable approach to keep up the development in circuit density is to change from CMOS based worldview to nanoscale extends. The primary favorable circumstances of such circuits high speed, high design
