M.Sc. Björn Driemeyer
I studied electrical engineering at the University of Ulm where I received my B.Sc degree in 2018 and my M.Sc degree in 2020.
Beside my studies, I worked on several research projects dealing with RF hardware system design, 3D-RADAR grid-mapping and THz-sensing manufacturing. My masters-thesis covered the “investigation of dynamic-element-matching in high-speed delta-sigma ADCs”.
In July 2020 I started working towards my Ph.D. degree at the Institute of Microelectronics at the University of Ulm under the supervision of Prof. Dr.-Ing. Maurits Ortmanns. My research topic is the implementation of linearization techniques of wide-band, high-speed continuous-time delta-sigma ADCs.
