1. A voltage multiplier comprising:

  • a first clocked multiplier stage having an input and an output;

    a second clocked multiplier stage having an input and an output;

    an input level regulator having an input coupled to receive a supply voltage, a control input, and an output coupled to the input of the first multiplier stage; and

    a feedback bias control circuit coupled to the control input of the input level regulator, wherein the feedback bias control circuit is further coupled to receive the output of the second multiplier stage, and wherein the feedback bias control circuit generates a feedback signal for regulating an output voltage at the output of the input level regulator to a continuous range of voltage levels based on a comparison between a voltage proportional to a voltage at the output of the second clocked multiplier stage and a reference voltage.
