Abstract

In low-power systems, traditional power measurement techniques using Analog-to-Digital Converters (ADCs), amplifiers, and current sense resistors present a number of practical challenges; especially if one desires to monitor many components on a low power platform. This work introduces our novel digital method that attempts to minimize and/or eliminate the use of analog components while obtaining highly accurate measurements at fine resolutions using minimal power. Through our preliminary experiments, we have verified that our technique can be applied to accurately measure the power consumption of board and integrated circuits (IC) while eliminating measurement noise. Our on-going research seeks to refine and validate the core idea for measuring subcomponent power on board as well as within ICs.
