📄 原文摘要

University of Lisboa, Lisbon, Portugal 1 2 In an energy harvesting (EH) system for the internet of things (IoT), the input voltage VIN may vary within a wide range, e.g., from 0.3 to 1.8V from a solar cell, while the battery voltage VBAT and output voltage VOUT are usually higher than VIN. Figure 31.6.1 shows a dual-mode DC-DC converter for EH interface: Single-Input-Dual-Output (SIDO) and DualInput-Single-Output (DISO). In SIDO, the converter delivers power from source to both load and battery as POUT < PIN. Once POUT > PIN, the converter is in DISO mode, delivering both source and battery power to the load. A switched-capacitor (SC) converter is favorable for low-power EH interfaces. Previous works have used two-stage schemes [1, 2], i.e., not converting PIN directly to POUT or PBAT. This could isolate inputs or outputs, however, is not area efficient. In [3] and [4] a series multiplexer MUX for channel
