Abstract
A method of amplifying an input voltage based on cascaded charge pump boosting includes storing, by a first capacitor, first electrical charges corresponding to an input voltage to obtain a second voltage. The method further includes amplifying, by a voltage amplifier, the second voltage according to the first electrical charges stored by the first capacitor to obtain a third voltage. The method further includes storing, by a second capacitor, second electrical charges according to the third voltage. The method further includes amplifying, by the voltage amplifier, the third voltage according to the second electrical charges stored by the second capacitor to obtain a fourth voltage.
