High-voltage charge pump using low-voltage technology

A method, comprising:

• obtaining, by a first circuit of a charge pump circuit, charge sourced from a power supply operative at a first voltage level, wherein the first circuit comprises a first plurality of transistors arranged sequentially between the output of the power supply and a reference corresponding to ground, and wherein each of the first plurality of transistors is rated for operation at an applied voltage that is less than the first voltage level;
• storing the charge in a first capacitor of the first circuit at a first point in time;
• transferring the charge stored in the first capacitor to a second capacitor of a second circuit of the charge pump circuit at a second point in time such that the second capacitor stores the charge, wherein the second point in time is subsequent to the first point in time;
• transferring the charge sourced from the power supply to the second capacitor via a first diode that is coupled to the power supply and the second capacitor;
• transferring a second charge stored in the second capacitor to a third capacitor of the charge pump circuit at a third point in time that is subsequent to the second point in time, wherein a terminal of the third capacitor is coupled to a load that is driven by the charge pump circuit;
• and
• transferring a third charge sourced from the power supply to the third capacitor via a second diode that is coupled to the power supply and the third capacitor.
