Abstract

A logic signal controlled switching video amplifier is disclosed having minimal power dissipation. By utilizing diode and transistor amplifier switching techniques, charging and discharging currents in the video amplifier are controlled. The stray capacitance associated with circuit wiring and cathode ray tube interelectrode capacitance can be rapidly switched without requiring low impedances or high DC current levels in the video amplifier.
