April 1, 2019

Christian Schmidt, research associate at the Fraunhofer HHI, completed his dissertation “Interleaving Concepts for Performance Enhancement of High-Speed Digital-to-Analog Converters" at the Technical University of Berlin (TU Berlin) with summa cum laude.

The examination board chaired by Prof. Dr.-Ing. Lars Zimmermann (TU Berlin) consisted of the experts Prof. Dr.-Ing. Friedel Gerfers (TU Berlin), PD Dr. med. Volker Jungnickel (TU Berlin / Fraunhofer HHI) and Prof. Dr. med. Sebastian Randel (Karlsruhe Institute of Technology).

In his doctoral dissertation, Christian Schmidt explored the limitations and possibilities of two innovative interleaving techniques for digital-to-analog converters to realize a transmitter with higher bandwidth for optical communication systems. The main focus of his thesis is on the analog multiplexing DAC, as well as on the frequency interleaving DAC, both of which increase the bandwidth of the composite DAC.

Christian Schmidt began his work at the Fraunhofer HHI in 2018. In the Department of Photonic Networks and Systems, he is researching the broadband signal generation for optical communication technology.
