چکیده
Among emerging technologies, Quantum-dot Cellular Automata (QCA) is an attractive alternative for transistor based technologies. In this paper, novel efficient Quantum-dot Cellular Automata (QCA) devices are proposed that provide 3-input and 4-input AND & OR gates. These gates have simple structure and are efficient in term of cell counts, complexity and latency. These components are suitable for designing QCA circuits. Furthermore, we designed a 4-to-1 multiplexer in only one cycle clock by using the proposed 3-input AND gate. In addition this design is compared to other multiplexers in terms of area, complexity, latency and gate count. In order to prove the functionality of the proposed devices as well as 4-to-1 multiplexer, QCADesigner tool is utilized 1 .
