  • Abstract
    The authors introduce a new biquadratic tunable gm-C amplitude equalizer structure for correcting sinc(x)-distortion of video D/A converters. Unlike previously reported equalizers, the structure realizes independent electronic control of ω0 and Q by means of gm tuning, allowing simple compensation for active device nonideal effects. A design example is given, demonstrating the tunability and superior equalizer performance when compared with other structures. Simulation and measured results are included in the paper
