  • PhD. in Electrical Engineering, Katholieke Universiteit Leuven, Belgium, 1996. 
  • Researcher at imec, Belgium, 1996 – today: imec Fellow since July 2020 
  • Part-time lecturer at Vrije Universiteit Brussel, department ETRO since 2000. 
  • Today: part-time “hoogleraar” at ETRO, teaching Analog Electronics at the Master’s level 
  • Promoter of 21 past PhDs and 15 ongoing PhDs 
  • Since 2012 member of the program committee of the International Solid-State Circuits Conference (ISSCC), which is the flagship conference in the field of Integrated Circuit design. Chair of the RF subcommittee of ISSCC since 2016. Vice program chair for ISSCC 2022. Program chair for ISSCC 2023.
  • Member of the technical program committee of the European Solid-State Circuits Conference from 2007 to 2020. 
  • Past associate editor of the IEEE Transactions of Circuits and Systems – Part I 
  • More than 300 publications in conferences, journals, … 
  • Author of five books,  among which “Distortion analysis of Analog Integrated Circuits”, which is considered as a standard work in the field of analog IC design. 
  • Editor of one book. 

Today our daily life cannot be imagined anymore without electronics. For our work, communications, safety, healthcare, entertainment and in our cars we rely on integrated circuits (ICs) and miniaturized sensors such that they have become a commodity and that we almost forget their presence. All experts, not only in the field of electronics, unanimously agree that the importance of integrated circuits in the future will even grow in all fields mentioned above. Here are just two examples: many companies, not only car manufacturers, are looking into autonomous driving. This can only be made possible with an enormous increase of the number of ICs in a car and of their functionality. Another example is the insatiable need for faster wireless communication of more and more data: everyone and everything wants or has to be connected to the internet, people want to download or transfer high-resolution movies over the air without having to wait for minutes and minutes, … 

As of today, most of you are using a 4G smartphone while 5G is being rolled out. With several PhD students and in close collaboration with imec we are already preparing for 6G. To have a preview on 6G, please read https://www.eoswetenschap.eu/technologie/zo-zal-6g-er-vermoedelijk-uitzien (Dutch) and https://www.imec-int.com/en/press/new-imec-research-program-pursues-development-scalable-and-energy-efficient-6g-device  

The evolution mentioned above is only possible thanks to the incredible advance of the technology of integrated circuits, mainly the CMOS technology. At the time that I made my Msc. thesis, I have been using 3 micron CMOS, today my PhD. students play with 28nm CMOS and some of them are looking into … 3 nanometer, a difference in feature size of 1000 compared to my Master’s thesis!  

The enormous downscaling of CMOS over the years has led to a huge increase of the complexity of chips: a smartphone today is millions of times more powerful that all of NASA’s combined computing in 1969. For example, using 28 nm CMOS one can fit a few million gates into one square millimeter.  

Complex digital systems that are put on a chip (so-called “systems on chip”) need to rely on analog electronics. First of all, they have to interface with the outside world that is analog. To this end, analog interface electronics is used. Examples are the electronics between the antenna of a cell phone and the digital heart of the smart phone, the electronics that transform incident light on the pixel cells of a camera into digital signals, … Next, a digital system on a chip relies on analog circuits for its proper operation, namely for clock generation, power management, temperature control, … 

In terms of number of transistors, analog integrated circuits are much simpler than digital circuits, for which the number of transistors on one chip can be higher than one billion. With the further evolution of electronics, it is expected that the importance of analog integrated circuits will grow and the demand for analog IC design engineers will increase. Already today, the involved companies are fighting for talented analog IC designers and more work needs to be done with too little people. 

"My ultimate goal is to coach and train students and researchers in analog/RF/mm-wave IC design."

My role at the university is to train future engineers in analog integrated circuit design. I teach the basics of analog IC design at the Msc. level and I supervise several PhDs. With my function at imec, I can bring the students into contact with big industrial players that collaborate with imec in the field of analog/RF/mm-wave IC design. In this way, my courses of analog electronics as well as the PhD. subjects remain industrially relevant.
