1. A voltage multiplier for producing a multiplied output voltage from a supply voltage, comprising:

  • a first voltage multiplying stage for receiving the supply voltage as a power input, for producing at an output, a first multiplied voltage based on the supply voltage;

    means for rectification having an input for receiving said first multiplied voltage and having an output;

    a second voltage multiplying stage comprising;

    a capacitor having a first plate connected to the output of said means for rectification and having a second plate;

    an inverter powered by the first multiplied voltage, having an input receiving a timing control signal and having an output connected to the second plate of said capacitor such that the first plate of said capacitor is charged to the first multiplied voltage responsive to the output of said inverter being low, and such that the second plate of said capacitor is biased to the first multiplied voltage when the output of said inverter is high to produce a second multiplied voltage at the first plate of said capacitor.
