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.

Circuits & Systems Group in DAC 2021



We are thrilled to announce that our group's research paper entitled "Local Bayesian Optimization for Analog Circuit Sizing" has been accepted in the 58th Design Automation Conference, to be held during December 5-9, 2021 in Moscone West, San Francisco, CA.

The article is co-authored by Konstantinos Touloupas and Paul P. Sotiriadis.

Cover of “Technologies” Journal Featuring Our Work



We are thrilled to announce that the article "Analog Realization of Fractional-Order Skin-Electrode Model for Tetrapolar Bio-Impedance Measurements" was selected for the cover of the MDPI scientific journal “Technologies” 2020, 8 (4).

The article was co-authored by Vassilis Alimisis, Christos Dimas, Georgios Pappas, and Paul P. Sotiriadis; you can access it here.

Participation in the development of the “EPIDOSE: A privacy-preserving epidemic dosimeter based on contact tracing”



We are pleased to share that our group designed the hardware and developed the embedded firmware for EPIDOSE within the framework of collaboration with the Open Technologies Alliance (GFOSS) (https://gfoss.eu/).

EPIDOSE is an autonomous and portable, open-software, open-hardware device helping in monitoring the COVID-19 pandemic’s spread. It is based on Bluetooth technology and uses contact tracing to notify its user in the event of a confirmed COVID-19 case encounter, while fully respecting its user’s privacy. More information and details about the EPIDOSE can be found in the following link: https://github.com/eellak/epidose.

ICM 2020 Best Paper Award



We are pleased to announce that the paper entitled "Analogue Realization of Fractional-Order Healthy and Cancerous Lung Cell Models for Electrical Impedance Spectroscopy" received the Best Paper Award (1st place) in the IEEE 32nd International Conference on Microelectronics (ICM) that was held virtually on December 14-17, 2020.

The award-winning paper was co-authored by Vassilis Alimisis, Christos Dimas and Paul P. Sotiriadis; you can read it here.
