Event-Driven Circuits and Systems: A Promising Low Power Technique for Intelligent Sensors in AIoT Era

Abstract

This brief presents an overview of current trends in the level-crossing based even-driven systems for wireless sensors in AIoT applications. We show that orders of magnitude improvement in power consumption is possible with this promising low-power technique if we have a good understanding of the operation principle of the system, the ways of processing LC samples, and the selection of LC-ADC topology. We also present the research direction to extend the event-driven system for wide applications.
