Digitizers for electrophysiological signals and ultrasound imaging
用于电生理信号和超声成像的数字化设备
演讲内容简介
In this talk, we will look at two biomedical applications and how power-efficient ADCs and other mixed-signal techniques can be leveraged at the system level. Overall, this presentation will give insight in several biomedical applications, in various analog and mixed-signal design techniques, and aspects of overall electronic system optimization.
The first part of this talk deals with capacitive and dry-electrode based electrophysiological measurements. Such electrodes are hampered by increased noise levels and artefacts, higher electrode impedance, and variability. These various challenges are explained first, different amplifier, biasing, and motion artefact mitigation strategies are reviewed, and an exemplary multi-channel readout ASIC is discussed in detail, up to in-vivo characterization and signal processing for information extraction.
In the second part of the presentation, we will look at ultrasound imaging digitizers. We will look at fundamental and harmonic imaging and how a readout ASIC can be made adaptable to serve both. We will further investigate the design of small form-factor digitizers for multi-channel arrays, integration with power management functions, and strategies for clocking and performance adaptation to further enhance performance and efficiency.
演讲嘉宾介绍
Pieter Harpe (SM'15) received the MSc and PhD degrees from the Eindhoven University of Technology, The Netherlands, in 2004 and 2010, respectively. In 2008, he started as researcher at Holst Centre / imec, The Netherlands, where he worked on ultra low-power wireless transceivers, with a focus on ADC research and design. In April 2011, he joined Eindhoven University of Technology where he is currently an Associate Professor and lead of the Resource Efficient Electronics Lab. His main activities are on low-power analog and mixed-signal circuits, for instance for biomedical applications, internet of things, and edge AI. Dr. Harpe is TPC member for ISSCC and A-SSCC, Associate Editor for TCAS-I, SSCS AdCom Member-at-Large and SSCS Distinguished Lecturer. He previously served as TPC member for ISSCC, TPC member and track chair for ESSCIRC/ESSERC and co-organizer for AACD, was an IEEE SSCS Distinguished Lecturer in 2016/2017, and is recipient of the ISSCC 2015 Distinguished Technical Paper Award.
