Emerging Energy-Efficient Biosignal-Dedicated Circuit Techniques: A Tutorial Brief

Abstract

High spatiotemporal resolution biosignal that is vital for biomedical applications results in an information bottleneck that poses challenges for their transferring and processing. The energy efficiency of biosignal-dedicated circuits becomes increasingly important with the emergence of wearable and implantable healthcare devices where low power consumption must be fulfilled. This tutorial brief presents a concise overview of emerging energy-efficient biosignal-dedicated circuits from bandwidth- and computation-reduction perspectives, aiming to provide designers with a guideline for different design choices.
