Subject

My research focuses on a fully digital transmitter architecture, where as many components as possible should be integrated into a CMOS chip. A high efficiency of the individual components allows a high integration density, which reduces the costs for a transmitter. The efficiency of the power amplifier is particularly relevant because this is the main source of the total power loss. Therefore the central project is the study of a high efficient switching mode power amplifier in a FDSOI-CMOS technology.
