Abstract
A charge-based voltage multiplier device comprising a charge-pump circuit and a charge-pump controller is provided. The charge-pump circuit is configured to multiply an input voltage signal (Vin) into an output voltage signal (Vout), the charge-pump circuit includes a plurality of charge-pump stages, wherein at least one of the charge-pump stages includes a weighted capacitor array of pump cells. The charge-pump controller is configured to provide a pump cell select to selectively control the weighted capacitor array of pump cells of the at least one of the charge-pump stages of the charge-pump circuit.
