A voltage multiplier in which an n-phase circuit charges n-1 capacitors during the separate phases, then during the last or nth phase the capacitors are put in series to create n times the input voltage. MOS transistor devices are used to act as switches to charge a number of series connected capacitors. During a first phase of operation, the first in the series of capacitors is charged to a specific voltage to be multiplied by closing the MOS switches to place the voltage across the capacitor. During a next phase of operation, the first capacitor is disconnected by the switches and the next capacitor in series is charged to the input voltage. During successive phases of operation, successive capacitors are similarly charged. During the last phase of operation, the capacitors are connected in series with the voltage to be multiplied and are connected to an output capacitor. This places a total charge on the output capacitor which is equal to the sum of all the charges on the respective series connected capacitors plus the voltage to be multiplied. This results in an n+1 voltage multiplication wherein n is the number of series connected capacitors.
