Abstract
A D/A converter with a Gamma correction circuit according to the invention is designed for C-DAC which takes up much less space than the conventional R-DAC and 2-divided C-DAC. Therefore, this D/A converter has advantages of simple design and low cost. Furthermore, users can freely define the shape of a Gamma correction conversion curve to thereby widen application areas by adjusting terminal voltages.
