Abstract: Disclosed herein are related to a system and a method of amplifying an input voltage based on cascaded charge pump boosting. In one aspect, first electrical charges are stored at a first capacitor according to the input voltage to obtain a second voltage. In one aspect, the second voltage is amplified according to the first electrical charges stored by the first capacitor to obtain a third voltage. In one aspect, second electrical charges are stored at the second capacitor according to the third voltage. In one aspect, the third voltage is amplified according to the second electrical charges stored by the second capacitor to obtain a fourth voltage.
