Electrical circuit for voltage conversion

A voltage conversion circuit comprising:

• a multiple 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 switching inductive circuit electrically coupled in series with the multiple stage voltage converter and configured to:
• receive the intermediate signal;
• receive a comparison signal;
• and
• generate an output signal at a third voltage level based on the intermediate signal and the comparison signal;
• and
• a regulator circuit electrically coupled in parallel to the switching inductive circuit and configured to:
• receive the output signal;
• receive a reference signal at a fourth voltage level;
• receive a third clock signal;
• compare the output signal and the reference signal;
• and
• generate the comparison signal based on the third clock signal and the comparison of the output signal and the reference signal, wherein the switching inductive circuit 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 comparison signal.
