Current Research Interests


The ISDL focuses on developing core technologies for high-performance and low-power integrated systems. The applications range from power management ICs, high-speed high-resolution wire and wireless communication circuits and systems, sensor nodes and networks, to biomedical instruments. By uniquely combining power electronics and integrated circuits, and by having a good understanding of both the underlying process technology and the higher levels of system architectures, controls and operations, ISDL is committed to providing innovative solutions to high-performance integrated system designs beyond the semiconductor roadmap.
