Abstract
A MOSFET switching device, including first and second control terminals; a first MOSFET having its gate connected to the first control terminal; a second MOSFET having its gate connected to the second control terminal and its source and drain both connected to the source of the first MOSFET; and a third MOSFET having its gate connected to the second control terminal and its source and drain both connected to the drain of the first MOSFET. When complementary control signals are applied to the first and second control terminals, charge spikes occurring at the source and drain of the first MOSFET when the conduction state of the first MOSFET is changed are cancelled by charge spikes occurring simultaneously in the second and third MOSFET's.
