I am in my second year at the master's degree studying electronics/microelectronics and I need a topic for the dissertation thesis. My teacher told me to come up with ideas but I do not have any ideas. Some students chose to design some analog circuit + simulation + layout + physical implementation on a PCB. I would like to do this but I do not know what circuit to choose. Others chose projects involving microcontrollers and sensors and writing in C. This tempts me as well. And others I do not know. Can someone recommend me some dissertation topics. Thanks.
