Abstract
A circuit for driving a switched transistor comprises: a level shifter comprising at least one transistor, the level shifter configured to convert an input pulse to a pulse having a greater voltage swing than the input pulse and shift a voltage level of the converted pulse; and a pulse shaping filter coupled between the level shifter and the gate of the switched transistor, the pulse shaping filter tuned to cancel or reduce an impedance of the gate of the switched transistor. The switched transistor and/or the at least one transistor are a GaN High Electron Mobility Transistor (HEMT).
