Claim 13:
14. A waveform generator, comprising:
a first voltage stage comprising:
a first voltage source;
a first switch, wherein a first terminal of the first voltage source is coupled to a first terminal of the first switch;
a first ground reference, wherein a second terminal of the first switch is coupled to the first ground reference;
a first transformer having a first transformer ratio, the first transformer comprising:
a primary winding coupled to a second terminal of the first voltage source and the first ground reference; and
a secondary winding including a first end and a second end, wherein the first end is coupled to the first ground reference; and

a second voltage stage comprising:
a second voltage source;
a second switch, wherein a first terminal of the second voltage source is coupled to a first terminal of the second switch;
a second ground reference, wherein a second terminal of the second switch is coupled to the second ground reference;
a second transformer having a second transformer ratio, the second transformer comprising:
a primary winding coupled to a second terminal of the second voltage source and the second ground reference; and
a secondary winding including a first end and a second end, wherein the first end of the secondary winding of the second transformer is coupled to the second end of the secondary winding of the first transformer and the second end of the secondary winding of the second transformer is configured to be coupled to a load through a common node, wherein the secondary winding of the first transformer is coupled in series with the secondary winding of the second transformer, and wherein the first voltage stage further comprises a first diode coupled in parallel with the primary winding of the first transformer, and the second voltage stage further comprises a second diode coupled in parallel with the primary winding of the second transformer.
