Abstract

QCA (Quantum-dot Cellular Automata) is an alternative technology for CMOS that has a low power consumption and high density. QCA extensively supports the new plans in the field of nanotechnology. Applications of QCA technology as an alternative method for CMOS technology in nano-scale have a hopeful future. This paper presents the successful design, implementation and simulation of 2 to 1, 4 to 1 and 8 to 1 multiplexer with the minimum area as compared to the previous models in QCA technology. In this paper, by means of 4 to 1 multiplexers including D-Flip Flop (D-FF) structure in QCA, we present an 8-bit universal shift register. The structure of the 8-bit universal register is extendable to 16-bit, 32-bit and etc. In this paper, the successful simulation of 2 to 1, 4 to 1 and 8 to 1 multiplexers, including D-FF and finally 8-bit universal register structure in QCADesigner is provided. The multiplexers and D-FF presented in this paper have the minimum complexity, area and delay compared to the previous models. In this paper, the implementation of 8-bit universal shift register, by means of 4 to 1 multiplexers and D-FF are presented in QCA technique which have the minimum complexity and delay. In the proposed design of the 8-bit universal shift register, the faults are likely to occur at 2 to 1 multiplexers and D-FF. In this article, 2 to 1 multiplexers and D-FF are investigated from the cell missing and possible defects. Considering the pipeline being the virtue of QCA, the 8-bit universal shift register has a high speed function. This 8-bit universal shift register may be used in the high speed processors as well as cryptography circuits.
