A transformless high-voltage low-current push-pull amplifier using a DMOS (TMOS) power FET pair and capable of driving usual electrooptic (EO) loads with good linearity and sufficient bandwidth is presented. The implemented system provides a low-offset floating output up to 780 V point-to-point (p-p) maximum amplitude (1% distortion limit) for a differential input up to 7.0 V p-p. The maximum, open-circuit gain-bandwidth product for the stage exceeds 1.5 GHz, and its bandwidth decreases from 3.2 MHz to 200 KHz when the load capacitance
