M.Sc. Paul Kässer

Paul Kässer studied Electrical Engineering at the University of Ulm where he received his B.Sc. degree in 2018 and his M.Sc. in 2021. The topic of his Master thesis was ''Development and Test of a Mixed-Signal Neural-Network Processing-Element''.

During his bachelor studies, he did an internship in India at TVS Motor Company in control engineering, where he built a motion-controlled robot arm. At the end of his master studies, he pursued another internship at Qualcomm, where he was working in the field of Custom Design Automation.

Since September 2021 he is working as research assistant towards the Ph.D. degree under the supervision of Prof. Dr.-Ing Maurits Ortmanns. His research area is the system-level modeling and optimization of Sigma-Delta ADCs.


Online Tool for Rapid Continuous-Time ΣΔ Modulator Design

P. Kässer: ΣΔ A/D converters are the state of the art for many different applications. The basis for this type of A/D converter is the ΣΔ modulator. For a long time, discrete-time (DT) ΣΔ modulators dominated as their design techniques could easily be adopted to ensured high performance... [ more]
