Tutorial: Fundamental Circuits for Nanopower and Energy-Harvesting Applications

With the rising interest in edge computing, and the addition of AI/ML functionality, nanopower circuits are in great demand to reduce the quiescent power consumption of remote sensors. Moreover, due to limited battery size, energy harvesting is used to provide more power to sensors and to extend lifetime. In this tutorial, fundamental building blocks for nanopower circuits will be covered, including startupless lowvoltage references, low-frequency clocks, and LDO regulators. Energy harvesters as well as fundamental energy harvesting interface circuits will be surveyed. Attendees can expect a deep dive into fundamental and practical analog techniques to design nanopower systems.
