Shiqi Zhao, Chaoming Fang, Jie Yang, Mohamad Sawan

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.
