Abstract
A current variation reduction circuit for metal oxide semiconductor field effect transistors, which are controlled by the application of a drive voltage between the gate and drain terminals, includes a circuit for applying a compensation current to the gate terminal. The compensation current is of substantially equivalent magnitude and opposite polarity to current in the source to gate capacitance of the MOSFET in response to a change in the source to drain voltage of the MOSFET.
