Abstract: A 0.88pJ/bit 112Gb/s PAM4 transmitter is reported in 7nm FinFET CMOS with 1V ppd output amplitude. The quarter-rate TX architecture implements a 5-tap analog FFE using tap extension ...

Abstract: This article investigates a linear differential modulator driver for optical communication links beyond 120 GBd. The driver was implemented in a 55-nm SiGe ...
