resolution and good channel-to-channel uniformity are required in column-driver ICs. In conventional column-driver ICs, the resistor-DAC (R-DAC) architecture has been generally used due to its uniform characteristic, because each R-DAC in driver channels shares a common resistor string for gamma reference-voltage generation. Furthermore, nonlinear gamma correction can be easily implemented using a nonlinear resistor-string that has an inverse transfer curve to the liquid crystal (LC) response. However, the increase in color depth for LCDs results in a large chip-size overhead, thus disclosing the limitation of the R-DAC architecture. To overcome this issue, several hybrid DAC architectures composed of a main 6b R-DAC and a 4b sub-DAC with various interpolation schemes have been reported [1-5]. Their linear interpolation schemes reduce the driver channel size. Meanwhile, their linear 4b interpol
