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.
