Abstract :
A Manchester code generator designed at transistor level with NMOS switches is presented. This generator uses 26 transistors and has the same complexity as a standard D flip-flop. It is intended to be used in a complex optical communication system. The main benefit of this design is the use of a clock signal running at the same frequency as the data. Output changes on the rising edge and falling edge of the clock. The circuit has been designed in a 90 nm UMC CMOS technology to evaluate the efficiency of the proposed approach and experimental results show a correct behavior up to 5 Gbit/s data rate.
