Abstract
This paper presents a reconfigurable 56 GS/s
transmitter (TX) that operates up to 112 Gb/s with four-level
pulse-amplitude modulation (PAM-4) and at 56 Gb/s with non-
return-to-zero (NRZ) modulation scheme. Fabricated in the
10-nm FinFET technology, the TX incorporates a four-way inter-
leaved quarter-rate architecture with a three-tap feed-forward
equalizer (FFE). Key features of the TX include a 1-UI pulse-
generator-based 4:1 serializer combined with a current-mode
logic (CML) driver, low-powe
