Summary:Piezoelectric harvesters have been subject to a growing interest in recent years as they can provide a clean source of energy. To extract the power from the harvester, power conditioning circuits are required. In this article, a circuit is proposed to meet the requirements of relatively high efficiency, low voltage operation, good load regulation and sufficient DC output voltage. A combined cross-coupled rectifier and a switched capacitor DC-DC converter is designed and simulated in a CMOS 0.13 μm technology to provide a stable DC supply (1.2 V) to power integrated autonomous sensor systems.
