Distributed and networked sensors are increasingly important in the emerging era of the Internet of Things (IoT), as they are the gateway between the physical world and the ubiquitous electronics. This is the case in many modern-day applications ranging from smart cars to biomedical monitoring, environmental observations, energy control, etc.
Ultra-low power consumption in combination with the desired accuracy levels and absolute robustness are the main requirements for these sensors and their readout circuits. This can only be achieved by adopting innovative circuit architectures in combination with advanced technologies. This presentation will describe the state of the art of time-based sensor readout solutions, which have the benefit of small area and good technology scalability. An important requirement is the absolute robustness across temperature, etc. We will highlight the techniques used to accomplish this in time-based solutions.
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.
