Adaptive bandwidth control in a kinescope amplifier

摘要

A method for controlling dissipation in a video amplifier for a display signal. The method comprises the steps of setting a first current for establishing a first gain bandwidth product in the video amplifier. Generating a control signal in accordance with a slew rate of the display signal. Modifying the first current responsive to the control signal such that the video amplifier gain bandwidth product is controlled in accordance with the slew rate of said display signal.
