Claim 19:
20. The system of claim 17, wherein:
the first clamping device is a first active clamp comprising a first switch, a resistor, a first amplifier and a current source, and wherein:
the first switch having a drain connected to a gate of the power switch and a source connected to ground;
the first amplifier having an inverting input connected to the current source, a non-inverting input configured to receive a reference and an output connected to a gate of the first switch; and
the resistor is connected between the inverting input of the first amplifier and the gate of the power switch, wherein the first clamping device is configured to provide a negative voltage clamp for the gate of the power switch; and

the second clamping device is a second active clamp comprising a second switch and a second amplifier, and wherein:
the second switch having a drain connected to the gate of the power switch and a source connected to ground; and
the second amplifier having a non-inverting input connected to the gate of the power switch, an inverting input configured to receive the reference and an output connected to a gate of the second switch, wherein the second clamping device is configured to provide a positive voltage clamp for the gate of the power switch.
