A 100 Gb/s transceiver with GND-VDD common-mode receiver and flexible multi-channel aligner

A 5 Gb/s 20-channel transceiver uses 0.13 /spl mu/m 1.5 V CMOS technology. The sampling amplifier recovers /spl plusmn/100 mV 90 ps data over 0-1.5 V common-mode range. A flexible multi-channel aligner and full-digital CDR (clock/data recovery) architecture are used.
