Abstract
A voltage multiplier selectively couples an input voltage potential (10) from a voltage source (Vin) to an energy storage device (22) in response to a first control circuit (18). A second switching circuit (26) is used to selectively serially couple the first energy storage device (22) and the voltage source (10) to provide an intermediate voltage potential (Vin), which is selectively coupled to a second energy storage device (30) in response to a second control signal (28') that is provided by a second control circuit (38) coupled to the intermediate voltage potential (Vim). The output of the second energy storage device (30) comprises an output voltage potential (Vout) being greater than the input voltage potential (Vin).
