Abstract:
1. A MOSFET and a gate drive circuit adapted for very fast turn off for reduced crossover power losses, comprising a first MOSFET having a gate, a drain and a source for switching a load current equal to i at least a second MOSFET having a gate, a drain and a source for turning off the first MOSFET; the source of the first MOSFET and the source of the at least a second MOSFET being connected together as a source connection; the gate of the first MOSFET and the drain of the at least a second MOSFET being connected together as a drain-gate connection; the gate of the first MOSFET being characterized by having a very low gate resistance; the on resistance of the at least a second MOSFET being characterized by having a very low channel resistance; the source connection being characterized by having a very low impedance; and the drain-gate connection being characterized by having a very low impedance, so that when the at least a second MOSFET initially is turned on, and the first MOSFET begins to turn off, a gate current i and the gate current i
