Charge pump circuit having independent inverted and non-inverted terminals

A method of generating a bipolar output voltage having a magnitude which is multiple times a voltage level of a unipolar input supply, the method comprising the steps of:

• charging first and second transfer capacitors to the voltage level of the unipolar input supply;
• connecting the first and second capacitors in a first series arrangement and to a first reservoir capacitor such that a positive voltage equal to multiple times the voltage level of the unipolar input supply is applied to the first reservoir capacitor;
• and
• connecting the first and second capacitors in a second series arrangement and to a second reservoir capacitor such that a negative voltage equal to multiple times the voltage level of the unipolar input supply is applied to the second reservoir capacitor.
