Sensors are becoming ubiquitous in emerging applications such as wireless sensor networks and internet of things. An important requirement is a low energy consumption of the sensor and the sensor interface. This presentation will explore the fundamental limitations to the minimum energy required for such interfaces, and will give guidelines towards the design of low-energy interfaces. This will be illustrated with several practical designs, for both capacitive and resistive sensors. Also the impact of technology will be demonstrated, by presenting design examples in both CMOS and CNT technologies.
Georges G.E. Gielen received the MSc and PhD degrees in Electrical Engineering from the Katholieke Universiteit Leuven (KU Leuven), Belgium, in 1986 and 1990, respectively. He is full professor at the Department of Electrical Engineering (ESAT). From August 2013 Georges Gielen is also appointed as vice-rector for the Group Science, Engineering and Technology and Academic Personnel of the KU Leuven.
His research interests are in the design of analog and mixed-signal integrated circuits, and especially in analog and mixed-signal CAD tools and design automation. He is coordinator or partner of several (industrial) research projects in this area, including several European projects. He has authored or coauthored 7 books and more than 450 papers in edited books, international journals and conference proceedings. He is Fellow of the IEEE since 2002.
