Abstract
Quantum cellular automata (QCA) is a new method of computation used in designing of electronic digital circuits at scale of nanometers. QCA has been used to achieve better performance in cell density, high switching speed and low power dissipation. An adder is a very useful component used for designing of arithmetic digital devices. This paper presents a layout of full adder designed on single layer which is efficient in various aspects based on QCA technology proposed. The goal of the research is to minimize the cells used, designed area and delay in designing of full adder based on QCA. The proposed layout of full adder has been efficient in number of cells used, designed area as well as latency in clocks. The proposed layout has been designed using XOR gate and majority voter. The proposed layout of adder consist of 24 cells with an optimized area of 0.016 µm2 and 2-clock phases (~0.125 ps) which shows more efficient from previous work on adders. The layout of full adder has been successfully designed and simulated using QCADesigner-E 2.2.
