Multiplexer plays a dynamic role in the optimization of a digital circuit (FPGA, ALU and memory circuits etc) implementations. Due to continuous Scaling of CMOS device, has already reached to the minimum transistor size, hence , it is not possible to reduce the transistor dimensions further without scaling issues and functionality affect. QCA is one of the emerging and promising new nanotechnologies and is suitable to replace conventional CMOS technology, and potentially able to solve the physical limitations and challenges of CMOS scaling issues. In this paper, the proposed 2:1 multiplexer structure makes the use of inherent characteristics of QCA cells to act as an efficient multiplexer. The proposed QCA based multiplexer architecture improves 50% of design area, 29% of cell count and 75% of the cost when compared with the earlier designed best multiplexer architectures. Higher order multiplexers 4:1 and 8:1 are also designed using proposed 2:1 multiplexer which improved performance to a greater extent relative to existing efficient multiplexer architectures. The design and simulation of circuits have been performed using software tool QCA Designer Version 2.0.3.

Quantum dot Cellular Automata (QCA) is the alternative technology to the classic CMOS technology since it is going to attain a road block in reducing power consumption and increase speed of the digital circuits. Circuit switching network is the basic component in order to transmit input signal among the different users within the communication network. A novel crossbar switch is proposed in this paper to design this communication network. The basic building blocks of the proposed circuit Switching network are Crossbar switch, Multiplexer and Demultiplexer. Multilayer QCA cells are almost impossible when compared to the fabrication feasibility of the single layer design. So this design is achieved in single layer.Circuit switching network is designed and compared with existing one using QCA Designer2.0.3.The designs are verified through matching up with truth tables.

“…Quantum cell is the basic building block in QCA circuits, each cell has four quantum dots injected with two electrons moving between those dots [2]. QCA uses the arrangement of intracellular electrons for binary representation instead of voltage level, so there is flow of current in this technique [3][4][5]. Many efforts have been made to implement the crucial components in logic circuits such as XOR [6][7][8][9][10][11] and multiplexer [12][13][14][15][16][17][18] using this nanotechnology.…”

Quantum-dot Cellular Automata (QCA) is one of the most important computing technologies for the future and will be the alternative candidate for current CMOS technology. QCA is attracting a lot of researchers due to many features such as high speed, small size, and low power consumption. QCA has two main building blocks (majority gate and inverter) used for design any Boolean function. QCA also has an inherent capability that used to design many important gates such as XOR and Multiplexer in optimal form without following any Boolean function. This paper presents a novel design 2:1 QCA-Multiplexer in two forms. The proposed design is very simple, highly efficient and can be used to produce many logical functions. The proposed design output comes from the inherent capabilities of quantum technology. New 4:1 QCA-Multiplexer has been built using the proposed structure. The output waveforms showed the wonderful performance of the proposed design in terms of the number of cells, area, and latency.
