Abstract: Novel digital technologies always lead to high density and very low power consumption. One of these concepts is Quantum-dot Cellular Automata (QCA), which is one of the new emerging nanotechnology-based on Coulomb repulsion. This article presents three architectures of logical “XOR” gate, a novel structure of two inputs “XOR” gate, which is used as a module to implement four inputs “XOR” gate and eight inputs “XOR” gate using QCA technique. The two inputs, four inputs, and eight inputs QCA “XOR” gate architectures are built using 10, 35, and 90 Cells on 0.008 µm2, 0.036 µm2 and 0.114 µm2 of areas, respectively. The proposed “XOR” gate structure provides an improvement in terms of circuit complexity, area, latency and type of cross wiring compared to other previous architectures. These proposed architectures of “XOR” gate are evaluated and simulated using the QCADesigner tool version 2.0.3.
