Über Thomas Ußmüller

Lebenslauf

Im Jahr 2006 hat Thomas Ußmüller sein Diplom im Fachbereich Elektrotechnik, Elektronik und Informationstechnik von der Universität Erlangen-Nürnberg erhalten. Nach Abschluss seines Diploms arbeitete er als wissenschaftlicher Mitarbeiter am Lehrstuhl für Technische Elektronik. Dort wechselte er 2007 auf eine Stelle als Akademischer Rat und übernahm gleichzeitig die Leitung der Chip Design Gruppe. Im Jahr 2011 promovierte er sich dort zum Doktor der Ingenieurwissenschaften. Im März 2014 wechselte er an die Universität Innsbruck. Er leitet dort die Gruppe für Mikroelektronik und implantierbare Systeme.

    abstract = {This work presents a highly flexible mixed-signal CMOS image sensor suitable for smart camera applications. These systems need to fit different constraints regarding power consumption, speed and quality, and the optimal compromise may differ depending on the application. Moreover, the best implementation of a desired image processing task may be in the analog or the digital domain, or even a combined computation. Different aspects starting from the image sensor and signal acquisition up to the pre-processing in analog and digital domain are investigated in this paper to optimize not just one part of the system, but the whole system altogether. Moreover, it is shown that analog processing algorithms can improve signal quality, processing speed and latency while being able to save power, which is important for real-time systems. In order to be able to carry out spatial operations, the state-of-the-art sensor is modified to be able to read out multiple pixels at the same time. This allows analog spatial filter operations which consume significantly less power. As an example, an averaging filter is described which needs less than 5.3 % of the power–time product of a digital implementation for one computation. To enhance data throughput and flexibility, 3D chip stacking is proposed to partition the sensor in smaller units and enable massively parallel processing.},
