Speaker: Dr. Valentijn De Smedt

Bio: Dr. Valentijn De Smedt received his PhD degree from Katholieke Universiteit Leuven on the design of ultra-low-power time-based building blocks for wireless sensor networks in 2014. Between February 2014 and July 2017 he was employed at MinDCet as a Senior Design Engineer and was responsible for the IP development of ultra-high voltage (1 kV) high-power integrated power converters and motor drivers. From September 2016 to October 2017 he was part-time postdoctoral researcher at the KU Leuven technology campus in Geel. Since 2017 he is appointed as assistant professor in the ADVISE research group. The focus of his research is on radiation-tolerant control systems for power and sensing applications. At KU Leuven, he has been involved in both leadership and technical activities of the IEEE student branch and IEEE Benelux GOLD (Young Professionals). In November 2017 he founded the IEEE Benelux NPSS chapter, which he currently chairs.

Title: Radiation tolerant HV converters

Abstract: This seminar focuses on the design issues of ultra-high voltage (up to 1000 V), high-power integrated circuit design for radiation environments. Starting from a 1kV integrated motor driver, the impact of ionizing radiation is discussed and challenges are identified. A comparison is made between SoI and bulk silicon technologies in terms of hardness towards particle strikes and total ionizing dose. Circuit- as well as technology solutions will be discussed, showing the trade-off between HV and Radiation tolerance. Special attention will go to simulation issues in switched converters. The seminar ends with the (system) design of a 200V radiation tolerant GaN driver for space applications.

Speaker: Dr. Jeffrey Prinzie

Bio: Dr. Jeffrey Prinzie received his PhD degree from KU Leuven in 2017 in the field of radiation tolerant integrated circuits with the ADVISE research group. During his PhD, he was part of the CERN micro-electronics research group in which he was collaborating on a TDC SoC and high speed multi-gigabit transceiver and he gained experience in the design and experimental testing of these circuits in nuclear facilities. His current research focuses on highly digital integrated circuits, digitally assisted analog- and RF integrated systems and time accurate circuits for high-energy physics, space and nuclear energy applications. Currently, he is also a visiting researcher at Mediatek wireless (United Kingdom) on ultra-fast locking digital RF-frequency synthesizers for 5G mobile systems.

Title: Radiation effects and hardening techniques for integrated CMOS phase locked loops

Abstract: In the era of complex systems on chip (SoCs), clock and timing generation is required in nearly any application. These PLLs and timing generators supply clock signals to digital modules, act as heartbeats for serial communication links or provide picosecond accurate reference information to time-interval sensors. However, in the nuclear, space and high-energy physics applications, ionizing radiation effects degrade these circuits significantly and produce soft-errors which can disturb an entire system. In this seminar, the application of these timing blocks in harsh environment applications are discussed together with the mitigation techniques for ionizing radiation.
