We present the design of dual rail Data Driven Self Timed (DDST) DEMUX and MUX circuits for 50 GHz operation. The chosen current density is 6.5 kA/cm2 and simulations show good margins for speeds exceeding 50 GHz. Our previously reported dual-rail on-chip test system is also scaled up for 50 GHz operation.
