A New Cost-Efficient Design of a Reversible Gate Based on a Nano-Scale Quantum-Dot Cellular Automata Technology

Quantum-dot cellular automata (QCA) nanotechnology is a practical suggestion for replacing present silicon-based technologies. It provides many benefits, such as low power usage, high velocity, and an extreme density of logic functions on chip. In contrast, designing circuits with no waste information (reversible circuits) may further reduce energy losses. The Feynman gate has been recognized one the most famous QCA-based gates this purpose. Since reversible are significant, paper develops new optimized double that uses efficient arithmetic elements its key structural blocks. Additionally, we used several modeling principles to make it consistent more robust against noise. Moreover, examined suggested model compared previous models regarding complexity, clocking, number cells, latency. Furthermore, applied QCADesigner monitor outline performance proposed gate. results show acceptable improvement via designed in comparison existing designs. Finally, temperature cost analysis indicated efficiency nan-scale
