A horizontal deflection circuit for controlling the horizontal deflection of an electron beam in a cathode ray tube used, for example, in a video display. The circuit uses a plurality of MOSFET transistors, which are switched on and off in unison for switching between a scan mode and a retrace mode, the MOSFET transistors being cascaded to accommodate the high voltage levels which are developed during retrace. A retrace capacitor and retrace diode are connected between the source and drain terminals of each MOSFET transistor to ensure that the voltages are divided among the transistors so that the entire voltage does not appear across any single one if they do not all switch at precisely the same time. |
