Abstract: Portable and wearable diagnostic devices are the trend of the bio-medical field. In these devices, power consumption is very important. On the other hand, signals from bio-transducers are generally weak. In order to obtain accurate signal acquisition with limited power consumption, power efficiency is a critical design consideration.In this talk, the power efficiency of bio-acquisition circuits will be formulated and examined. A design example of a voltage-acquisition circuit and a current-acquisition circuit with state-of-art power efficiency will be illustrated.

Biography: Prof. Yuan received his Ph.D in Electrical Engineering from the University of Pennsylvania, Philadelphia, in 2006. He received his B.S in Electrical Engineering from Tsinghua University in 2000. From 2006, Prof. Yuan has been with the Electronic & Computer Engineering Department in Hong Kong University of Science & Technology, where he is an Associate Professor now.

Prof. Yuan’s research interest is on high-performance mixed-signal IC design for sensory applications. More specific research interests of his group include ultra low-power data converters, high-performance analog front-ends, and CMOS imaging sensors.

Dr. Yuan is a Senior Member of IEEE . He served as the Technical Program Committee Co-Chair of IEEE Biomedical Circuits and Systems Conference 2009. He is an Associate Editor of the IEEE Transactions on Biomedical Circuits and Systems. He was a Guest Editor of IEEE Transactions on Circuits and Systems I: Regular Paper. He served as the chair of the Biomedical Circuits and Systems Technical Committee 2012-2014.
