Welcome to the Emerging Circuits and Computation (ECC) Group

Our group, comprised of Mustafa Altun and his scholars & students, is in the Department of Electronics and Communication Engineering at Istanbul Technical University. In terms of research, we aim to develop new computing paradigms as well as circuit design and electronic design automation (EDA) techniques especially for future and emerging technologies. We also have a special interest in electronics reliability in both circuit and system levels. In terms of teaching, we offer courses on digital/analog circuit design as well as on computational nanoelectronics.
