1. A voltage conversion circuit comprising:

  • a first stage voltage converter configured to;

    receive an input signal at a first voltage level;

    receive a first clock signal and a second clock signal; and

    generate an intermediate signal at a second voltage level based on the input signal, the first clock signal, and the second clock signal;

    a second stage voltage converter electrically coupled in series with the first stage voltage converter and configured to;

    receive the intermediate signal;

    receive the second clock signal and a combined comparison signal; and

    generate an output signal at a third voltage level based on the intermediate signal, the combined comparison signal, and the second clock signal;

    a comparison circuit electrically coupled in parallel to the second stage voltage converter and configured to;

    receive a reference signal at a fourth voltage level;

    receive the output signal and the first clock signal;

    compare the reference signal and the output signal; and

    generate the combined comparison signal based on the first clock signal and the comparison of the reference signal and the output signal, wherein the second stage voltage converter is configured to adjust the third voltage level of the output signal to approach the fourth voltage level of the reference signal based on the combined comparison signal.
