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 work presents an 850-nm vertical-cavity surface-emitting laser (VCSEL)-based optical transmitter (TX) capable of reaching speeds of up to 50 Gb/s in the four-level pulse amplitude ...
