Peak detector and charge pump

Hi
Is there any difference between the charge pump and Dickson charge pump circuit?

Thanks

Most voltage multipliers have a final output stage which is a peak detector (like your schematic). Many voltage multipliers are made from Villard cells, that is, diode-capacitor pairs which act as charge-pumps.

The Dickson type is made from one or more H-bridges (using transistors or mosfets). These steer current (similar to diodes), and so a diode does not always appear in the final output stage.
