Title: Sensor Interface Circuits

Abstract: While IoE spans very diverse and broad application domains, a lot of those require extensive sensing. Individual nodes in the IoE can be equipped with a multitude of quite diverse sensors like gas, temperature, humidity, pressure, position and various biomedical sensors. Area-efficient, high-performance and low-power sensor interface design is thus an important prerequisite for successful deployment of IoE. This short course will address exactly these topics. A brief overview of various sensor types and how to interface them will be discussed. The unique design challenges for sensor interfaces will be addressed. The short course will discuss in-depth state-of-the-art instrumentation amplifier designs as well as trans-impedance amplifier designs both of which are at the heart of a lot of sensor interfaces. Advanced circuit design techniques like chopping, bootstrapping, offset cancellation will be explained. Finally a look into novel and promising research areas like time-domain sensor interface design will conclude the short course.

Bio: Nick Van Helleputte received the MS degree in electrical engineering in 2004 from the Katholieke Universiteit Leuven, Belgium. He received his Ph.D. degree from the same institute in 2009 (MICAS research group). His PhD research focused on low-power ultra-wide-band analog front-end receivers for ranging applications. He joined imec in 2009 as an Analog R&D Design Engineer. He is currently team leader of the biomedical circuits and systems team. His research focus is on ultra-low-power circuits for biomedical applications. He has been involved in analog and mixed-signal ASIC design for wearable and implantable healthcare applications. Nick is an IEEE member and served on the technical program committee of VLSI circuits symposium and ISSCC.
