A B S T R A C TThis paper introduces a peculiar approach of designing Static Random Access Memory (SRAM) memory cell in Quantum-dot Cellular Automata (QCA) technique. The proposed design consists of one 3-input MG, one 5-input MG in addition to a (2×1) Multiplexer block utilizing the loop-based approach. The simulation results reveals the excellence of the proposed design. The proposed SRAM cell achieves 16% and 15% improvement in terms of total number of Cell counts and Area. Similarly, the proposed design structure realizes the overall power dissipation savings up to 35.3% at maximum energy dissipation of circuit, 38.6% at average energy dissipation of circuit, 36.1% at minimum energy dissipation of circuit, 36.4% at average energy dissipation of circuit and 40.1% at average switching energy dissipation compared to the latest reported designs. The power analysis and structural analysis of the proposed design is compared with its state-of-the-art counterpart designs, using QCAPro and QCADesigner 2.0.3 tools. The proposed QCA based SRAM cell design can be taken as a base design in building an ultralow power information generating systems like Microprocessors.

“…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. The multiplexer (MUX) was extensively utilized to implement many digital circuits such as RAM cells and ALU.…”

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.

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.
