该论文提出了一种完全自主的多输入单电感多输出能量收集与电源管理平台,通过集成最大功率点跟踪和多模态冷启动技术,实现了32nA的超低静态电流和1.2×10^5的动态范围,解决了自供电物联网设备中多源能量收集与高效电源管理的难题。
Shuo Li, Xinjian Liu, Benton H. Calhoun University of Virginia, Charlottesville, VA Energy harvesting and power management units (EHPMUs) are gaining popularity for self-powered Internet-of-Things (IoT) applications due to their ability of extracting ambient energy and powering load circuits through a single block. Among all EHPMU architectures, the multi-input single-inductor multi-output (MISIMO) [1-6] has the benefits of small form factor, high efficiency, extracting energy from multi-modal energy sources, and powering different types of loads. Self-powered IoT applications also require the EHPMUs to have ultra-low quiescent power, wide dynamic range, and autonomous features to support their deployment without any battery. However, previous EHPMUs either consume too much power [1-3] or only provide a small dynamic range [4,5]. They also suffer from two-stage power delivery causing cascaded power loss [1,5] and lack
