Abstract
This article presents an 86.71875-GHz RF
transceiver IC featuring a fully integrated clock and data
recovery (CDR)-assisted carrier synchronization loop (CSL) for
waveguide links. The carrier frequency of 86.71875 GHz is chosen
to be the third harmonic of the baseband null frequency of
28.90625 GHz, and the carrier synchronization is achieved using a
baseband CDR instead of power- and area-intensive RF circuits.
The IC, fabricated in 28-nm CMOS, demonstrates 57.8125-Gb/s
pulse-amplitude modulati
