A 34 Gb/s Distributed 2:1 MUX and CMU Using 0.18$muhbox m$CMOS

A 34 Gb/s 2:1 serializer consisting of a CMOS MUX and CMU using a 0.18$muhbox m$SiGe BiCMOS process is presented. The serializer is based on distributed amplifier topology realized using spiral inductors. The circuit also includes an on-chip 2-channel$2^7-1$PRBS generator. The 34 Gb/s serial output has single-ended voltage swing of 380 mV with rise/fall time of 13 ps, and measured ISI is less than 5 ps p-p.
