Design of First Adder/Subtractor Using Quantum-Dot Cellular Automata
Ali Shahidinejad, Ali Selamat · Advanced materials research · 2011
Quantum-dot cellular automata (QCA) is an emerging nanotechnology that provides faster speed, smaller size and lower power consumption compared to the current transistor-based technology. Adder/ subtractor is a useful component for the design of many computation systems and functional circuits. This paper proposes a practical XOR design in QCA. Then the first adder/subtractor circuit in QCA is designed and simulated using the proposed XOR design. Results of simulation were carried out using QCADesigner.
