M.Sc. Dominik Fritschi

Dominik Fritschi received the B.Sc. and M.Sc. degrees in electrical engineering from the University of Ulm in 2021 and 2024, respectively. In his Bachelor Thesis and as a student assistant, he worked in the field of neuromodulators. The topic of his master thesis was "Design of ADCs in fineline CMOS at cryogenic temperatures".
From April to October 2023, he worked as an intern in the custom design automation team at Qualcomm Technologies Inc. (Cork, Ireland). Since September 2024, he is working towards his Ph.D. at the Institute of Microelectronics under the supervision of Prof. Dr.-Ing. Maurits Ortmanns.
