Claim 12:
13. A fast switching circuit for driving a transistor gate of a transistor switch, the circuit comprising:
a first charge pump configured to receive a power high supply voltage and to generate a boosted power high supply voltage greater than the power high supply voltage;
a first switch stack coupled between the first charge pump and an output node that controls the transistor gate;
a second charge pump configured to receive a power low supply voltage and to generate a boosted power low supply voltage less than the power low supply voltage; and
a second switch stack coupled between the second charge pump and the output node,
wherein the first charge pump and the second charge pump are configured to output one of the boosted power high supply voltage or the boosted power low supply voltage during a switching state of the transistor switch, and
wherein the first charge pump comprises a first transistor coupled between a third supply voltage and a first node and configured to receive a positive precharge control signal, a second transistor coupled between the power high supply voltage and the first node and configured to receive a positive discharge control signal, and a first capacitor coupled between the first node and a second node.
