Postdoctoral Fellowship in Control for Digital-to-analogue Converters and Switched Systems
The University of Stavanger invites applications for a 3-year, research-only Postdoctoral Fellowship at the Faculty of Science and Technology with an anticipated start in August 2021, as part of the research project “Ultra-linear Digital-to- analogue Conversion” funded by the Norwegian Research Council.
The project aims to develop methods for digital-to-analogue conversion enabling a dynamic range in excess of 1 part-per-million, at high speed and with low latency, using advanced control theory and dithering techniques in combination with the latest CMOS fabrication technology. This level of performance has never been achieved before and will define the new state-of-the-art in the field.
High-resolution digital-to-analogue conversion and control has a wide array of applications, including adaptive optics, semiconductor lithography, fabrication, and inspection, laser interferometry, metrology (measurement science), imaging and manipulation in microbiology, chemistry, materials science, and scanning probe microscopy in general. Furthermore, methods relating to analogue-digital conversion will have major impact in renewable energy production and distribution, and communications technology.
The group you will be joining has used dithering techniques to build the highest resolution digital-to-analogue converter known in the literature and will serve as the starting point of the current project. The project is a collaboration between the University of Stavanger, Norwegian University of Science and Technology, Aalborg University, Justervesenet (Norwegian Metrology Service) and Eindhoven University of Technology, as well as The University of Newcastle, Australia.
The objectives for this position are to develop mathematical models of digital-to-analogue converters and control schemes for optimal switching of output elements, focusing on:
- developing models amenable to mathematical analysis
- model comparison with existing commercial CMOS simulation tools
- applying model-based, optimal control schemes, e.g., model-predictive control
- developing sub-optimal control schemes with low computational load (e.g., dithering)
