Abstract:
This article presents a power- and area-efficient switched-capacitor (SC) ac–dc converter in low-voltage (LV) CMOS for mains-powered Internet of Things (IoT) applications. The proposed converter adopts a single-stage series-capacitor architecture with fine-grained pre-rectification regulation, eliminating the need for intermediate high-voltage (HV) dc capacitors or HV dc–dc stages, thereby …
