Abstract :
High-speed and low-power operation of a 1:4 demultiplexer IC with a multi-phase clock (MPC) architecture is reported. The architecture features four parallel latch lines and a toggle flip-flop (TFF) that generates a four-phase clock. The IC, which was fabricated using InP HEMTs, exhibited 50-Gbit/s error-free operation with a power consumption of 1.42 W. Compared to a conventional tree-type InP HEMT 1:4 demultiplexer IC, the IC with the MPC architecture operates at the same operating speed with only one-quarter the power consumption.
