    Abstract: An integrated circuit driver system utilizing Metal-OxideSilicon Field-Effect Transistors (MOS FET''s) is disclosed for operation in a two-phase mode for driving a substantially capacitive load. A preferred embodiment of the invention makes use of an alternating current (ac) voltage having a peak-to-peak magnitude somewhat greater than the direct current (dc) supply potential. An auxilliary dc power supply is implemented for converting the ac voltage to an operating potential for inverters which in turn provide the phase inverted signals required by a pair of drivers. The latter generate the alternate phases of the output voltage presented to the load. Additionally, the system exploits the MOS threshold voltage dropping properties to realize a threshold shift of suitable magnitude to insure the required duty cycle of the driver output pulse waveforms.
