Performance of future VLSI system is limited by its interconnect bandwidth, power, performance and other fundamental physical limitations (such as mechanical reliability, thermal constraints, overall system form factor, etc.). Especially the interconnects in VLSI system, it has been predicted to be the ultimate limitation of the overall system performance in consumer electronics, high speed connector, high speed memory interface and future network-on-chip. Therefore, the interconnect system in future VLSI requires to have ultra-high data rates, scalable, re-configurable, highly compact and reliable interconnect fabric. In order to adopt such rapid evolution in future interconnect in both on-chip and chip-to-chip communication, I would like to explore the use of multiband RF/Wireless-Interconnects which can communicate simultaneously through multiple frequency bands with low power signal transmission, reconfigurable bandwidth and excellent mechanical flexibility and reliability. My future research will focus on RF/Wireless-Interconnect in four different potential application domains, which include Network-on-Chips (NoCs), advanced memory interface, ultra-high speed contactless connectors and ultra-low power wireless-interconnect technology. In addition, I would like to further investigate multi-band oscillator and reconfigurable meta-material from mm-wave up to TeraHertz frequency.


Dr. Sai-Wang (Rocco) TamDr. Sai-Wang (Rocco) Tam was born in Hong Kong. He received his B.Sc., M.Sc. and Ph.D. degree in electrical engineering from the University of California, Los Angeles, in 2003, 2008 and 2009, respectively. His current research interests include high speed mixed-signal circuits, mm-wave circuits, RF/Wireless-interconnect and network-on-chip. He has been published 15 conference papers/journals and 1 book chapter. Dr. Tam recent paper "CMP Network-on-chip Overlaid with Multiband RF-Interconnect" was selected for the Best Paper Award in 2008 IEEE International Symposium on High-Performance Computer Architecture (HPCA). From 2008 to 2010, he was the founding member of an early stage mm-wave semi-conductor company, WaveConnex Inc, Los Angeles, CA. In this position, Rocco successfully demonstrated and developed the first ultra-short distance mm-wave (60GHz) wireless system. Currently, he has been working in an early stage start-up RFID company, TagArray Inc, Palo Alto, CA, where he is currently a project leader supervising a team of 6 engineers to develop the next generation sub-microwatt UWB-RFID system.
