  • Patent number: 4860107
    Abstract: A video signal is coupled from the output of a display driver amplifier to an image display device via a coupling network including cascaded emitter follower transistors of opposite conductivity type. First and second diodes are respectively connected across the base-emitter junctions of each transistor and are poled for forward current conduction in a direction opposite to that of the associated base-emitter junction. The coupling network significantly reduces the value of capacitance of the display device as presented to the output of the driver amplifier, thereby improving positive and negative video signal transient response.
