Harvard Mixed-Signal VLSI

Combining Circuits & Architecture to Combat Variability

Gu-Yeon Wei

 

Research

My research group focuses on various aspects of mixed-signal VLSI circuits and system design. We have multiple projects in high-speed links and building blocks that investigate techniques to push performance and reduce power. We are actively pursuing projects related to collaborative software + architecture + circuit techniques to efficiently tackle variability in nanoscale IC technologies in collaboration with architecture and systems groups at Harvard.  We also investigate how to combine circuits and architecture to build ultra-low-power computing devices for wireless sensor networks.

A narrative of my research activities can be found here and my updated CV here.
