Claim 22:
23. The method of claim 18, further comprising:
generating a third voltage pulse at the common node at a third time by closing a third switch that has a first terminal and a second terminal, wherein:
the first terminal of the third switch is coupled to a first terminal of a third voltage source;
a second terminal of the third voltage source is coupled to a first terminal of a primary winding of a third transformer, the third transformer having a third transformer ratio;
the second terminal of the third switch is coupled to a second terminal of the primary winding of the third transformer and to ground;
a second bias voltage is generated by the third voltage source between the first terminal and the second terminal of the third voltage source; and
a first terminal of a secondary winding of the second transformer is coupled to a second terminal of the secondary winding of the first transformer.
