Techniques for Analyzing and Reducing Voltage Conversion Ratio Transition Losses of Capacitive DCDC Converters for Fast-DVS-Enabled Systems

Switched-capacitor (SC) converters have numerous advantages in supplying fast and fine-grained voltages to microprocessors. However, the losses associated with the voltage conversion ratio (VCR) transition, which has not been investigated in detail, may cause a significant efficiency drop. This letter presents a simple and accurate model for estimating energy losses during the VCR transition of ma...
