Design of a compact and low-power TDC for an array of SiPM's in 110nm CIS technology
(Institute of Electrical and Electronics Engineers, 2017)
Silicon photomultipliers (SiPMs) are meant to substitute photomultiplier tubes in high-energy physics detectors and nuclear medicine. This is because of their -to name a few interesting properties- compactness, lower bias ...

In the quest of vision-sensors-on-chip: Pre-processing sensors for data reduction
(Society for Imaging Science and Technology, 2017)
This paper shows that the implementation of vision systems benefits from the usage of sensing front-end chips with embedded pre-processing capabilities - called CVIS. Such embedded pre-processors reduce the number of data ...
