Design of Reversible and Non- Reversible Binary to Gray and Gray to Binary Converter using Quantum Dot Cellular Automata

The advancement in technology increases day by day, that the conventional based CMOS VLSI technology reached its peak due to physical limits like power dissipation and size. In order to overcome this, a new alternative method has introduced to recurrently improve the development of digital electronics. Quantum-Dot Cellular Automata (QCA) approach is nanotechnology which is an emerging technology provides an efficient platform to overcome the confines of existing CMOS. In this research investigation a novel design of 4-bit reversible and non-reversible binary to gray (B-G) and gray to binary code (G-B) converter was simulated with the help of QCA tool and the obtained results were found to be efficiently better when compared with that of the previous one.
