I co-designed following three ICs during the course of my Ph.D. These included my circuit design ideas that were published later in IEEE journals/conferences. I would like to thank CMC for providing access to leading IC manufacturing technologies through their prototype manufacturing program. They also provided EDA tools to design these ICs, compute infrastructure to run EDA tools, and test equipments to test these chips once fabricated.
