Abstract
A wide-tunable current-mode (CM) gamma corrector for HDTV camera applications is proposed. This gamma corrector provides accurate gamma control over a wide range by simple electrical adjustment of the gain of the weighting amplifier. It has a wide signal bandwidth of >40 MHz. Sufficient for HDTV video signal processing, and can be implemented using a simple integrated circuit with low power consumption
