Abstract :
This paper describes the 100-Gb/s multiplexing operation of a selector IC and demultiplexing operation of a D-type flip-flop (D-FF) using production-level 0.1-μm-gate-length InP HEMT IC technology. To boost the operating speed of the selector IC, a selector core circuit directly drives an external 50-Ω load, and is included in the output stage. In addition, a test chip containing the selector and a D-FF to confirm error-free operation of these circuits was designed. The fabricated selector IC exhibited clear eye openings at 100 Gb/s, and its error-free operation was confirmed by using the test chip.
