Kandilakis, E. (author), Serdijn, W.A. (author), Akgün, O.C. (author)In this paper, we present the design of a low-voltage, low-power, and small-area time-mode ADC (TM-ADC) for bio-signal sensing applications. The proposed time-mode ADC (TM-ADC) consists of a programmable oversampling ratio (OSR), voltage-controlled ring oscillator (VCRO) based analog-to-time converter (ATC), followed by an asynchronous unfolded...conference paper 2021

Akgün, O.C. (author), Nanbakhsh, K. (author), Giagka, Vasiliki (author), Serdijn, W.A. (author)One key obstacle in employing silicon integrated circuits in flexible implants is ensuring a long-term operation of the chip within the wet corrosive environment of the body. For this reason, throughout the years, various biocompatible insulating materials have been proposed, yet, evaluating their long-term encapsulation performance on...conference paper 2019

Gancedo Reguilon, Alberto (author), Akgün, O.C. (author), Serdijn, W.A. (author)This paper presents the design of an extremely low-energy biosensing platform that utilizes voltage to time conversion and time-mode signal processing to sense and accommodate electrophysiological biosignals that will be later sent remotely using a simple and low power communication scheme. The electrode input is fed to a chain of monostable...conference paper 2019
