We have some funding for new image sensor research opportunities. If you want to do some cool research on CMOS image sensors, contact me and I can tell you more.
Update 31/3/2022: ESA has published new high-resolution images taken with the EUI. You can see the sun in detail as never before: https://www.esa.int/Science_Exploration/Space_Science/Solar_Orbiter/Zooming_into_the_Sun_with_Solar_Orbiter
We developed the extreme-uv sensitive backside thinned CMOS imagers for the EUI instrument at CMOSIS in collaboration with ROB (Brussels) and CSL (Liege). That was a truly Belgian project, rare to see that happen in our kingdom today.
Great to see the detectors in full action now, delivering stunning images. Also the PHI instrument, for which we developed the imagers and built by Max Planck Institute for Solar Physics, shows great pictures. Check ESA’s article and movie:
Here’s ESA movie telling more about the mission and the the ‘first light’ for the orbiter’s instruments, including EUI and PHI:
More on EUI detector design can be found, for example in the paper accessible via this link. Check also other publications in my publication list:
Since a few weeks, all IISW 2021 papers are available online on https://imagesensors.org/2021-papers/
Together with Albert Theuwissen of TU Delft and Harvest Imaging, I wrote a tutorial article on column ramp AD converters. Starting from the basic architecture of ramp converters, the article dives deeper into circuit aspects such as the comparator design, the benefits of counters over latches and the limitations of the architecture . The article is published in the inaugural issue of “Foundations and Trends in Integrated Circuits and Systems”, a new journal that provides short monographs, overview and review articles on a specific topic in the field, edited by prof. G. Gielen (KU Leuven). It can be found here: https://www.nowpublishers.com/article/Details/ICS-002

Nice to see that first image – captured by the CMV20000 image sensor inside the rover’s engineering cameras. I can’t wait to see the full resolution pictures.
A great milestone for the entire team that developed this chip back at CMOSIS. Who could have thought at that time that this imager would ever end up on Martian surface? The initial application was quite different 😉
I took the role of co-editor in-chief of a special issue of MDPI Sensors Journal on the IISW 2019. Fifteen of the best publications of IISW 20219 were invited for an extended paper. Thanks to the commitment of the authors and the work of our co-editors Johannes Solhusvik, Mike Guidash and Rihito Kuroda, it became an excellent collection of articles discussing how CIS technology is being advanced.
You can access the papers here. Enjoy them!
