Also, QCA supports the new devices with nanotechnology architecture. This technique works based on electron interactions inside quantum-dots leading to emergence of quantum features and decreasing the problem of future integrated circuits in terms of size. In this paper, we will successfully design, implement and simulate a new 2-input and 3-input XOR gate (exclusive OR gate) based on QCA with the minimum delay, area and complexities. Then, we will use XOR gates presented in this paper, in 2-bit, 4-bit and 8-bit controllable inverter in QCA. Being potentially pipeline, the QCA technology calculates with the maximum operating speed. We can use this controllable inverter in the n-bit adder/subtractor and reversible gate.}, keywords = {Exclusive OR(XOR) gate,Inverter,Majority Gate,Quantum-dot Cellular Automata(QCA)}, url = {https://www.ijnnonline.net/article_6117.html}, eprint = {https://www.ijnnonline.net/article_6117_77887abb402c5ffd6484f1e27ac00869.pdf} }
