A Manchester code generator running at 1 GHz

A new Manchester code generator designed at transistor level is presented in this paper. This generator uses 32 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 to use a clock signal running at the same frequency as the data. Output changes on the rising edge and falling edge of the clock. Simulations results show a correct behavior up to 1 Gbit/s data rate with a 0.35 /spl mu/ CMOS technology within a commercial temperature range.
