Paper by ECE-NTUA Ph.D. candidates V. Alimisis and C.Dimas receives the Best Paper Award in ICM 2020

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 (Ph.D. candidate, ECE NTUA), Christos Dimas (Ph.D. candidate, ECE NTUA) and Paul P. Sotiriadis (Professor, ECE NTUA).

ABSTRACT: This work proposes an integrated-circuit architecture emulating healthy and cancerous lung cell behaviors, approximated by Cole models and is suitable for calibration and phantom experimental testing of electrical bioimpedance circuits and systems. The architecture is based on fractional-order elements implemented with both active and passive components, offering an accurate transfer function behavior between 10kHz and 1MHz. The high-level architecture includes an analog all-pass filter coupled with a current conveyor. Performance and accuracy of the proposed architecture is confirmed via Monte-Carlo simulation. The proposed circuitry has been designed in TSMC 90nm CMOS process and simulated using the Cadence IC suite.
