Abstract
A high energy efficiency switched-capacitor power converter includes the transmission gates T-T, the capacitors C-C, the load capacitor CL, and resistors, PMOS tubes and NMOS tubes. The power converter converts a stable input voltage of 3V into an output voltage of 1V by means of charge transfer. In the state of timing sequence, the on-chip capacitor C, the capacitor Cand the load capacitor CL are charged in series. In the state of timing sequence, the capacitor Cand the capacitor Care connected in parallel to the capacitor CL to supplement the charge loss due to load for the capacitor CL. When the establishment is completed, the voltages across the capacitor C, the capacitor C, and the capacitor CL are basically the same. At this time, the voltage drop across the switch tube approximates 0 V during the charge transfer process.
