Fully On-Chip Charge Pump-based Boost Converter in 65-nm CMOS for Single Solar Cell Powered IC

This paper introduces a novel design approach and a prototype of a fully on-chip charge pump (CP)-based boost converter for integrated circuits powered by single solar cells. Measured performance proves the effectiveness of the proposed architecture and design strategy. Comparison with other integrated energy harvesting solutions based on CPs shows that the proposed solution occupies the lowest area with a comparable power conversion efficiency. Moreover, the power density is about 2.5 times higher than the best value reported.
