Claim 7:
8. A circuit, comprising:
a pulse generator;
a first current path coupled between a floating voltage and a negative bootstrap circuit, the first current path including a first current generator coupled through a first resistor to the floating voltage at a first node of the first current generator, and the first current generator coupled to be controlled by a first pulse signal generated by the pulse generator; and
a second current path coupled between the floating voltage and the negative bootstrap circuit, the second current path including a second current generator coupled through a second resistor to the floating voltage at a first node of the second current generator, and the second current generator coupled to be controlled by a second pulse signal generated by the pulse generator,
wherein the negative bootstrap circuit includes a pump capacitor, a first terminal of the pump capacitor coupled to a second node of the first current generator and a second node of the second current generator, and a second terminal of the pump capacitor selectively coupled to one of a first voltage potential or a second voltage potential controlled by one or more of the first pulse signal or the second pulse signal.
