Abstract A 10‐bit TFT‐LCD column driver with hybrid DACs is proposed. The data conversion is implemented by an R‐DAC and a C‐DAC, which are used for the MSB and LSB data conversions, respectively. The simulated results show that the DAC exhibits the maximum DNL and INL of 0.28 LSB and 0.35 LSB, respectively. The settling time is within 4 μs. The areas for one R‐DAC and one C‐DAC are 0.438 × 1.063 mm 2 and 0.207 × 0.11 mm 2 , respectively.
