<p>An output driver circuit (100, 200, 10, 300, 500) comprising a plurality of multiple gate field effect transistors (e.g. 12, 14) (MGFETs) that provides an output signal (30) is provided. Each output driver circuit may have a first MGFET gate for receiving a drive signal (11, 13), a second MGFET gate for biasing purposes (22, 24), and a current electrode for providing an output signal (30). Some embodiments provide a drive signal (11, 13) and a bias signal (22, 24) to the same MGFET device. Alternate embodiments provide the same drive signal (211) (or alternately the same bias signal (213)) to both gates of the same MGFET device (212, 214). Some embodiments may provide an output driver circuit (100) having variable output impedance. Predriver circuitry (236) and/or bias control circuitry (240) may optionally be used.</p> |
