Abstract
The invention is related to methods and apparatus for driving transistors. One embodiment includes a driver circuit that can drive power transistors at relatively high switching speeds, which can advantageously decrease the size of associated electronics systems that use the driver circuit and power transistors. Embodiments of the invention can drive a switching device that needs a negative voltage bias in order to be shut off. For example, the switching device can correspond to a junction field effect transistor (JFET). Advantageously, one embodiment of the invention can drive such switching devices on and off from a single positive voltage supply.
