초록
A novel wide-tunable quadratic gamma corrector for HDTV camera applications is proposed. The new gamma corrector controls gamma value in a wide range by simple electrical adjustment of multipliers' gain. It has wide signal bandwidth of 30MHz sufficient for HDTV applications. It also simplifies the circuit design, resulting in a compact surface mounting board implementation with reduced power consumption. Simulation and experimental results confirm these characteristics.
