title = "Novel Switched-Capacitor DC-DC Converter Achieving Highest Rational Conversion Ratios Using Inter-Stage Feedback",
abstract = "This paper proposes an inter-stage feedback-based switched-capacitor (IFSC) converter that can be configured to realize any rational voltage-conversion ratio (VCR) using a minimum number of 2:1 switched-capacitor (SC) stages. The converter enables efficient dynamic voltage scaling (DVS) operation over a larger voltage range by significantly increasing the resolution of voltage levels. Additionally, a restructuring algorithm has been proposed to achieve all VCRs without requiring any additional dedicated voltage stages. The converter extends the idea of the recursive switched-capacitor (RSC) topology, which spans 2N -1 ratios with N 2:1 SC cells. Comparative analysis shows that the proposed converter outperforms the negative-output feedback-based converter in terms of bottom-plate parasitic loss for most VCRs. To validate the concept, a fully-reconfigurable hardware prototype has been developed.",
