Ultra-low Power Sentry for Ambient Powered Smart Sensors

摘要

The basic circuit operation of the power sentry system was presented previously in the 3rd Quarterly Report, but it has been updated and included again as a reminder. The proposed power sentry system requires several components to realize the signal processing technique for monitoring a sensor output to detect the presence of signals with defined frequency and amplitude properties. In this section, each component's role within the system will be described to provide a general understanding of how the implemented circuit design performs the desired function.
