Welcome to the Circuits & Systems Group Website


The Circuits & Systems Group is located at the School of Electrical and Computer Engineering of the National Technical University of Athens, Greece. It was founded in 2013 by professor Paul-Peter Sotiriadis and as of today it counts more than 30 members, including 11 Ph.D. candidates and 16 Master thesis students.

Our group leads in modeling, evaluation and design of integrated and discrete circuits and systems, covering a wide area in the field of electronics. More specifically, our main research directions include but are not limited to: analog and digital IC design, CAD automation tools, sensors' and sensor systems' development, unconventional computing techniques, biomedical systems and instrumentation, and others.



Our News

Professor Paul Sotiriadis was named IEEE Fellow!

We are thrilled to announce that Prof. Paul Sotiriadis of the School of Electrical and Computer Engineering - NTUA (National Technical University of Athens) has been named a 2023 IEEE Fellow for his contributions to Advanced Frequency Synthesis and High-Speed Data Buses. This is a great recognition of his contributions to two important technical areas: Frequency Synthesis, which is of fundamental importance to Radar, Telecommunications, Navigation, Timing, Instrumentation and other systems, and, (on-chip) High-Speed Data Buses (optimization) for increasing on-chip data transmission speed and power efficiency. His work has been adopted by the industry and has been included in technical books, which is an important criterion for elevation to the Fellow level. IEEE Fellow is one of IEEE's most prestigious Honors and the highest grade of IEEE membership, awarded to a very limited number of Senior Members who have made significant contributions to the advancement or application of Engineering, Science and Technology. According to the IEEE Fellows Directory, Prof. Sotiriadis is the only IEEE Fellow in the technical area of Integrated Circuits in Greece, one of the 8 IEEE Fellows who are members of our School, and, one of the 26 IEEE Fellows in Greece.


Best Paper Award in the IEEE SBCCI 2021

We are pleased to announce that the paper entitled "A 0.6V , 3.3nW, Adjustable Gaussian Circuit for Tunable Kernel Functions" received the Best Paper Award in the IEEE 34th Symposium on Integrated Circuits and Systems Design (SBCCI 2021) that was held virtually on August 23 to 27, 2021.

The award-winning paper was co-authored by Vassilis Alimisis (Ph.D. candidate, ECE NTUA), Marios Gourdouparis (Diploma Student, ECE NTUA) Christos Dimas (Ph.D. candidate, ECE NTUA) and Paul P. Sotiriadis (Professor, ECE NTUA).
