Abstract
High-speed, low-power optical interconnects, such
as intensity modulation direct detection (IMDD) optical links,
are increasingly deployed in data centers to keep pace with
the growing bandwidth requirements. High-sensitivity low-power
optical receivers (RXs) are the key components that enable
energy-efficient IMDD optical interconnects. This article presents
a low-power nonreturn-to-zero (NRZ) optical RX using a combi-
nation of a limited-bandwidth trans-impedance amplifier (TIA)
and duobinary sa
