A Wide Input Power Line Energy Harvesting Circuit For Wireless Sensor Nodes
… aims to harvest energy from AC powerlines with a wide input range of from 10 to 50 A. The proposed system includes a wake-up circuit and is capable of cold-start. A buck-boost converter operating in DCM is adopted for impedance matching, where the impedance is rather independent of the operation …

Design of a wide input supply range buck-boost converter
… flexibility of stepping-up and stepping-down the input supply to generate a regulated output, thus making them very attractive for applications with wide input supply range. Currently, off-the-shelf buck-boost converters require a minimum operating voltage of 1.8V. As a result, the operating …

High Efficiency Topologies for Dual Voltage Inputs
… that can operate at the full Universal Mains range. The main reasons for this trend are logistics and travel reasons. The above reasons drive the requisite for low-cost, small, high-performance, improved efficiency and broad input range power supplies. The main limitation of the existing …

Energy management techniques for ultra-small bio-medical implants
… second part of this work develops techniques for wide-input-range energy management. The first chip implementing stacking suffered an efficiency penalty by using a switchedcapacitor voltage regulator with only a single conversion ratio. In a second implementation, we introduce a better solution …

Bridge to digital converters for environmental monitoring in edge IoT devices
… Converters (BDCs), which need to have high input impedance and gain, be linear, and have offset and noise levels similar to those of the WhB. This work proposes three bridge-to-digital conversion solutions to address challenges in resistive sensor-based monitoring systems. First, it …
