Abstract
A wide-tunable current-mode (CM) gamna corrector for HDTV camera applicatio ns is proposed. This gamma corrector provides accurate gamma control over a wide range by simple electrical adjustment of the gain of the weighting am plifier. It has a wide signal bandwidth of > 40 MHz, sufficient for HDTV vi deo signal processing, and can be implemented using simple integrated circu it with low power consumption.
