Design of Binary to Gray Code Converter for Error Correction in Communication Systems Using Layered Quantum Dot Cellular Automata

Due to the expeditious growth of digital industry, the transistor based CMOS technology endures serious challenges due to the scaling of the device dimensions at nano scale. Quantum Dot Cellular Automata is an emerging domain in the province of nanotechnology that uses quantum dots to process and transfer information which works on the combined postulates of quantum mechanics and cellular automata to overcome the disputes of the transistor technology. This paper has demonstrated the use of Layered T gate for designing binary to gray code converter based on Quantum Dot Cellular Automata. The paper has also presented the application of binary to gray code converter for error corrections in communication systems. The proposed design is superior as compared to the existing designs in terms of cell count, area and latency. The layout has been generated and functionality of the design has been verified using the QCA Designer simulation tool.
