Matryoshka CSCR: A Reconfigurable Matryoshka-Stacked Continuous-Scalable-Conversion-Ratio Switched-Capacitor DC-DC Converter with 0.1-to-1.7V Input
This paper presents a reconfigurable continuous-scalable-conversion-ratio (CSCR) switched-capacitor DC-DC boost converter, named Matryoshka CSCR converter, for energy harvesting (EH) applications. With 6 split-input CSCR cores adaptively stacked like Matryoshka dolls, the structure significantly extends the voltage conversion ratio (VCR) range with small M and N numbers. The chip was fabricated in a 180nm process. It covers 0.1-1.7 V input for a 1.8-V output and achieves 88.6% peak efficiency and 23.8mW peak power.
