High voltage swing and high data rate multiplexers in SiGe technology

A 2:1 time-division multiplexer with high differential output voltage swing of 2/spl times/2 V/sub pp/ operating at a data rate of 40 Gb/s is reported. The circuit shows rise and fall times of about 11 ps and consumes 1.65 W. It is fabricated in 0.35 /spl mu/m/200 GHz-f/sub T/ production-near SiGe bipolar technology with a V/sub CE0/ of 1.8 V. Furthermore a high-speed 2:1 multiplexer capable of processing data rates higher than 80 Gb/s has been realized in the same technology. It consumes 0.75 W.
