Fundamentals

Our research on fundamental limits and analytical study of issues pertain to integrated circuits and sensors. We continue to be interested in a deep understanding the underlying fundamental limitation to the performance of integrated circuits, which has enabled us to come up with non-trivial disruptive solutions, topologies and architectures.
