1. A circuit for improving switching performance of a three terminal switch comprising:

  • said three terminal switch having a source for electrons, a drain for electrons, and a control terminal having an internal capacitance between the control terminal and the source for electrons; and

    means for amplifying a current for modifying a charged state of said internal capacitance;

    wherein said means for amplifying the current comprises a transistor having an emitter, collector, and base;

    said modification of said charged state takes place across said collector and emitter; and

    said base controls said amplification of current in synchronisation with the switching of the three terminal switch; and

    wherein said means for amplifying the current further comprises a diode connected between the control terminal of the three terminal switch and the collector of the transistor.
