Dr.-Ing. Johannes Wagner

I studied electrical engineering at the University of Ulm, where I received my B.Sc. degree in 2012 and my M.Sc. degree in 2015. During my Bachelor I focused on material science for electrical devices resulting in the Bachelor thesis with the title "Herstellung von Probenträgern für Hallmessungen an Graphen in-situ in einem Transmissionselektronenmikroskop". My master was focused on microelectronics. I finished it with the Master thesis titled "Model Extension of an Online Tool for the Heuristic Design of CT Sigma-Delta Modulators".

In September 2015 I began my work at the University of Ulm and received the Dr.-Ing. degree under the supervision of Professor Dr.-Ing. Maurits Ortmanns in May 2021. My research area is the system-level modeling and optimization of Sigma-Delta ADCs.
