Abstract
A static load for a high voltage driver includes first and second depletion mode field effect transistors and a diode-connected enhancement mode field effect transistor. The static load is arranged with a switching transistor to form a high voltage driver circuit. When the output of the driver circuit is at a relatively low potential, current drawn from the high voltage power supply is substantially reduced by applying a source to gate potential through the diode-connected transistor to one of the depletion mode transistors below the threshold voltage of the depletion mode transistor.
