Single-Channel Heterogeneous-Source Energy Harvesting PMIC Design

This work proposes an energy harvesting platform that is able to convert power from both DC sources (photo-voltaic cells and TEGs) as well as piezo element sources. It does so only using a single input channel to which a single harvester can be connected. The proposed system is able to differentiate between the two source...

A Switched Capacitor DC-DC Buck Converter for a Wide Input Voltage Range

In this paper, a power-efficient multiphase Recursive Switched Capacitor (RSC) converter is presented. Conventionally, RSC converters are used to obtain many different output voltages from a fixed input voltage. Here, the converter provides a fixed output voltage of 1 V at 1 mA from an input voltage ranging from 1.4 V to 4.5 V. It has one...
