Abstract :
A 500-MHz bandwidth, high-precision monolithic video driver IC for the next-generation leading CRT display with 4 Mpixels or more is described. Based on a novel circuitry design, the driver IC was fabricated by a 2.5-μm complementary-bipolar-transistor array. It has a multi-output current amplifier, a gain controller, a video multiplexer, and a sample-and-hold bias circuit. The IC realizes a new wide-bandwidth (250-300 MHz) CRT video amplifier scheme; a current-mirror-driven cascade amplifier with a low-voltage feedback is used for DC restore
