Encoding processes are getting more significant in communication. Methods such as Miller, Manchester, and FM0 encoding can be applied in different applications. Each method has a different processes which are based on their needs. Each encoding system should be applied without losing any of its parameters. The fully-reused VLSI architecture of FM0, Manchester, and Miller encoders has reduced the number of transistors and keeps the DC balance. In this Paper, working for the Manchester and Miller Encoder. Manchester and Miller Encoder can work in High Frequency without use sophisticated circuit structure.
