Session 16 Overview
High-Speed mm-Wave Circuits
Chair: K. R. (Kumar) Lakshmikumar, Conexant Systems, Red Bank, NJ
Associate Chair: Jae-Yoon Sim, Pohang University of Science and Technology,
Pohang, Korea
Very high speed wireline and wireless communication systems offer many opportunities and challenges.
There are two different approaches to realize such systems. The first one is to employ modulation techniques
that make more efficient use of the limited available bandwidth. The other approach is to take
advantage of the advancements in CMOS process technology to build ever faster circuit functions like
equalization, clock and data recovery, etc. The papers in this session give a flavor of both these approaches
covering emerging applications such as 100G Ethernet, mm-wave wireless 100GHz-range sensing
and imaging, and anti-collision radar systems.
As the data rate exceeds 10Gb/s, the limited bandwidth of the channel poses severe problems for NRZ
data. Duobinary coding absorbs a significant amount of channel loss to introduce a controlled amount
of ISI that can be removed at the receiver. Paper 16.1 from NEC describes a duobinary receiver in a 90nm
CMOS operating at a data rate of 18Gb/s with power consumption of 100.2mW from 1.2V supply.
