Dr. Yong Lian received the B.Sc degree from College of Economics & Management of Shanghai Jiao Tong University in 1984 and the Ph.D degree from the Department of Electrical Engineering of National University of Singapore (NUS) in 1994. He worked in industry for more than 9 years before joining NUS in 1996. He was appointed as the first Provost’s Chair Professor in the Department of Electrical and Computer Engineering of NUS in 2011. His research interests include low power techniques, continuous-time signal processing, biomedical circuits and systems, and computationally efficient signal processing algorithms. He has received more than US$30 million in research funds from various sources.Dr. Lian received more than 20 awards for his research including the 1996 IEEE Circuits and Systems Society's Guillemin-Cauer Award, the 2008 Multimedia Communications Best Paper Award from the IEEE Communications Society, 2011 IES Prestigious Engineering Achievement Award, 2012 Faculty Research Award, 2013 Outstanding Contribution Award from Hua Yuan Association and Tan Kah Kee International Society, 2014 Chen-Ning Yang Award in Science and Technology for New Immigrant, and the latest 2015 Design Contest Award in 20th International Symposium on Low Power Electronics and Design. He is also the recipient of the National University of Singapore Annual Teaching Excellence Awards in 2009 and 2010, respectively.
Dr. Lian is the President of the IEEE Circuits and Systems (CAS) Society, a member of IEEE Fellow Committee, Steering Committee member of the IEEE Transactions on Biomedical Circuits and Systems. He was the Editor-in-Chief of the IEEE Transactions on Circuits and Systems II for two terms from 2010 to 2013. He served many positions in the IEEE CAS Society including Vice President for Publications, Vice President for Asia Pacific Region, Chair of the Biomedical Circuits and Systems Technical Committee, Chair of DSP Technical Committee, Distinguished Lecturer, etc. He is the founder of several conferences including BioCAS, ICGCS, and PrimeAsia.
Internet-of-Things (IoT) is the inter-networking of physical devices, vehicles, buildings, and objects with embedded sensors. The edge of IoT may contain different types of sensors and actuators. With the advancement of system-on-chip (SoC), the edge devices such as smart sensors become more powerful and integrate more connectivity options. They are able to perform tasks such as filtering, pre-processing, aggregating or scoring raw data. It is estimated that by 2020 there will be more than 34 billion devices connected to the Internet. Nearly $6 trillion will be spent on IoT solutions over the next five years. As most of sensors in IoT edge devices are energy constraint, a major challenge in the design of embedded edge SoCs is to lower power consumption. This talk will cover low power techniques for wireless embedded SoC for IoT applications. The focus is on the energy efficient system architecture that utilizes the continuous-in-time and discrete-in-amplitude (CTDA) signal flow. The CTDA signal flow enables data compression at the input source, which greatly reduces the power for wireless data transmission. Design example, such as smart wireless ECG (electrocardiogram) SoC, will be discussed in detail to illustrate the benefits of CTDA system architecture.
