N2 - This paper presents a fully-integrated reconfigurable switched-capacitor (SC) converter that extracts power from a 1. 5-1.SV input voltage and regulates a 0. 3-1.SV output voltage. The converter employs a proposed output-boosting scheme that increases the output voltage of the conventional 3-ratio SC converter power-efficiently. Therefore, the voltage conversion ratios increase from 3 to 14 without the need for additional cascaded SC converter stages. The proposed converter was designed and simulated with a 0. 1S\mum CMOS process and achieved a peak efficiency of 86.7% and a maximum output current of 0.8 mA.
