Claim 19:
20. A waveform generator, comprising:
a first voltage stage, comprising:
a first voltage source;
a first switch; and
a second switch, wherein
a first terminal of the first voltage source is coupled to a first terminal of the first switch,
a second terminal of the first voltage source is coupled to a first terminal of the second switch and an output node of the waveform generator,
the second switch is disposed between a first node and the output node,
a second terminal of the first switch is coupled to the first node and a second terminal of the second switch, and
the output node is configured to be coupled to a load; and

a second voltage stage coupled between the first node and a ground node, wherein the first node is disposed between the second terminals of the first switch and the second switch, wherein the first voltage stage is connected with the output node, and wherein the second voltage stage is coupled to the output node through the first voltage stage, the second voltage stage comprising:
a second voltage source;
a third switch; and
a fourth switch, wherein
a first terminal of the second voltage source is coupled to a first terminal of the third switch,
a second terminal of the second voltage source is coupled to a first terminal of the fourth switch and the first node,
the fourth switch is disposed between a second node and the first node, and
the second node is coupled to the ground node, a second terminal of the third switch and a second terminal of the fourth switch.
