Research Overview

Our research activities cover various aspects of mixed-signal VLSI circuits and systems 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 combine circuits and architecture to build high-performance, low-power computing devices via specialization for wireless sensor networks, chip multiprocessors, and the brain of our RoboBees.
