M.Sc. Elias Ruopp

Elias Ruopp studied Electrical Engineering at the University of Ulm, Germany, where he received the B.Sc. and M.Sc. degrees in 2022 and 2025, respectively. In his master’s thesis, he investigated concepts for a multi-stage conversion scheme of a continuous-time incremental delta-sigma modulator. In 2024, he joined the Wireless ADC Team at Infineon Technologies in Villach, Austria, as an intern. 

Since September 2025, he has been pursuing a Ph.D. degree at the Institute of Microelectronics, University of Ulm, under the supervision of Prof. Dr.-Ing. Maurits Ortmanns. His current research interests focus on high-precision continuous-time data converters.
