Claim 24:
25. A non-transitory computer-readable medium for generating a waveform, comprising instructions executable by one or more processors to
generate a first voltage pulse at a common node at a first time by closing a first switch that has a first terminal and a second terminal, wherein:
the first terminal of the first switch is coupled to a first terminal of a first voltage source;
a second terminal of the first voltage source is coupled to a first terminal of a primary winding of a first transformer, the first transformer having a first transformer ratio;
the second terminal of the first switch is coupled to a second terminal of the primary winding of the first transformer and to ground; and
the common node is coupled to a first terminal of a secondary winding of the first transformer; and

generate a second voltage pulse at the common node at a second time by closing a second switch that has a first terminal and a second terminal, wherein:
the first terminal of the second switch is coupled to a first terminal of a second voltage source;
a second terminal of the second voltage source is coupled to a first terminal of a primary winding of a second transformer, the second transformer having a second transformer ratio;
the second terminal of the first switch is coupled to a second terminal of the primary winding of the second transformer and to ground;
a first bias voltage is generated by the second voltage source between the first terminal and the second terminal of the second 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,

wherein the common node is disposed between the first terminal of the secondary winding of the first transformer and a load, and wherein the secondary winding of the first transformer is coupled in series with the secondary winding of the second transformer.
