This article presents a resonant DC-DC converter topology suitable for ultra-low power and low voltage applications. The presented topology is dedicated to energy harvesting sources in general and especially for Radio-Frequency RF sources. Main advantage of this converter is its autonomy, i.e., it operates from low voltage levels without the need of an external energy source or any other startup assistance...
In this paper, an autonomous low voltage and ultra-low power DC-DC converter is presented. This novel topology is inspired from the classical Armstrong oscillator structure. In addition to be self-powered and autonomous, this converter is suitable for high-impedance sources. Theoretical and simulation-based optimizations are used in order to design the converter. A fabricated prototype is tested....
