Abstract :
Ultra-high-speed 2-b multiplexer (MUX) and demultiplexer (DEMUX) ICs have been developed for next-generation optical fiber communication systems in the SONET (synchronous optical network), which will require data bit rates of about 10 Gb/s. The ICs were fabricated using a 0.5- mu m WN/sub x/-gate process and were operated up to 12 Gb/s by adopting a tree-type architecture with a large phase margin and a new on-chip transmission line called the ladder grounded coplanar line. These ICs are applicable to future optical fiber communication systems (STS-192) as key devices.<>
