Field effect transistor switch

A field effect transistor (FET) is designed to act as an off-on type switch by the control of a driver voltage applied to its gate electrode. A driver circuit, responsive to a toggling current, provides a control of gate electrode voltage. The circuit includes means for rapidly switching the FET on and off while drawing relatively low current in the off and on states. Improvements relate to means for speeding up turn on time and reducing charge transferred to the circuit being switched by the FET.
