research interests include the following topics.
·
High-speed
electronics for serial communication
This is a rapidly changing field at the heart of
computer and server design. The demands for bandwidth across backplanes and
midplanes have outpaced the advances in the interconnect bandwidth. Channel coding and equalization can
compensate for channel attenuation and dispersion. Design trade-offs between equalization,
power consumption, and data rates are a complicated optimization for
enhancing link performance. An
anticipated migration to optical interconnects poses a new set of
integrated circuit problems for high-speed electronics.
As digital circuits move into the domain of microwave
engineering, new challenges have emerged for maintaining reliable digital
signaling. The signal integrity of digital signals is impacted by bandwidth
limitations in the form of intersymbol interference and deterministic
jitter. Characterizing high-speed channels is essential to understanding
performance issues for digital communication.
·
Millimeter
wave electronics for wireless communication
Wireless access is omnipresent and providing faster
network connections to wireless devices inevitably means moving to higher
frequencies for communication. Silicon CMOS and Silicon Germanium processes
offer fast enough transistor to reach new levels of circuit complexity at
microwave and millimeter-wave technologies.
As the silicon and microwave research communities collide a new era
of signal processing and circuit challenges is emerging.
