Professor Tsao's main research interests include Communication Electronics, Integrated Circuits, Measurement and Instrumentation systems, and Communication System . In the past few years, he has published several papers on optical CDMA transmission techniques and presently, he is investigating the realization of highly linear multicarrier RF transmitters and key circuit blocks in 10- and 100-Gigabit Ethernet systems. Also, he has studied precision timing circuit techniques applied to automatic test equipments (ATEs). He has also been involved in the projects of designing and implementing high speed variable-length Ethernet packet switches and ASIC’s for Ethernet and Passive Optical Networks ( PONs).
