Journal ArticleDOI
A $160~\mu {\rm W}$ 8-Channel Active Electrode System for EEG Monitoring
Jiawei Xu,Refet Firat Yazicioglu,Bernard Grundlehner,Pja Pieter Harpe,Kofi A. A. Makinwa,C. Van Hoof +5 more
TL;DR: In this paper, an active electrode system for gel-free biopotential EEG signal acquisition is presented, which consists of front-end chopper amplifiers and a back-end common-mode feedback (CMFB) circuit.
Proceedings ArticleDOI
A 160μW 8-channel active electrode system for EEG monitoring
TL;DR: To reduce the total power dissipation, this paper proposes a biopotential monitoring system based on active electrodes with gain, which would require a power-hungry back-end to keep the total integrated noise at acceptable levels.
Journal ArticleDOI
Active Electrodes for Wearable EEG Acquisition: Review and Electronics Design Methodology
TL;DR: This paper reviews state-of-the-art bio-amplifier architectures and low-power analog circuits design techniques intended for wearable EEG acquisition, with a special focus on an AE system interfaced with dry electrodes.
Journal ArticleDOI
A Wearable 8-Channel Active-Electrode EEG/ETI Acquisition System for Body Area Networks
Jiawei Xu,Srinjoy Mitra,Akinori Matsumoto,Shrishail Patki,Chris Van Hoof,Kofi A. A. Makinwa,Refet Firat Yazicioglu +6 more
TL;DR: This paper describes an 8-channel gel-free EEG/electrode-tissue impedance (ETI) acquisition system, consisting of nine active electrodes (AEs) and one back-end (BE) analog signal processor, capable of recording 8- Channel EEG and ETI signals.
Journal ArticleDOI
A 769 μW Battery-Powered Single-Chip SoC With BLE for Multi-Modal Vital Sign Monitoring Health Patches
Shuang Song,Peter Vis,Chris van Liempd,Chris Van Hoof,Nick Van Helleputte,Mario Konijnenburg,Roland van Wegberg,Jiawei Xu,Hyunsoo Ha,Wim Sijbers,Stefano Stanzione,Dwaipayan Biswas,Arjan Breeschoten +12 more
TL;DR: An all-in-one battery powered low-power SoC for measuring multiple vital signs with wearables is proposed, allowing an unprecedented level of miniaturization leading to smaller component count which reduces cost and improves comfort and signal integrity.
