KINESCOPE DRIVER APPARATUS.

摘要

A complementary push-pull emitter follower amplifier is coupled between the output of a high voltage driver amplifier and the cathode of a kinescope for reducing the effective capacitance presented to the driver amplifier that is atributable to the kinescope cathode, socket, spark gaps and related stray capacitances. A secondary undesired capacitance of the follower amplifier is effectively reduced by regulating the collector emitter voltages of the push-pull follower output transistors at respective substantially constant values thereby improving parameters such as the slew rate and bandwidth of the overall video display system.
