Abstract :
A high-voltage video amplifier IC with an automatic white balance circuit has been developed for color television (CTV). The IC can automatically adjust the white balance of the CTV by detecting the CRT (cathode ray tube) cathode currents. This enables the TV production line to eliminate the adjustment process. The frequency response of the video signal amplifier is as high as 10 MHz, so that the IC meets the requirements for larger TV screens and higher resolution
