Low-Power Design Techniques for Temperature-Sensing Applications
Power consumption is a critical design consideration for many sensor applications. Battery-powered devices, such as smartphones and laptops, need thermal monitoring to effectively blend performance with battery life. Logging devices designed for cold chain tracking must have a long enough battery life to perform their mission. IoT-sensing devices can be made smaller, cheaper, and simpler to deploy in a wide variety of use cases if the power requirements are made to be sufficiently low. This application report discusses the techniques and data analysis behind the reduction of current consumed by IC temperature sensors.
