A general source driver IC used in TFT (Thin Film Transistor) LCD (Liquid Crystal Display) is non‐linear passive resistor string DAC (Digital to Analog Converter) architecture. However, It has the limits for satisfaction needs of market. In this paper, a new linear active resistor string DAC architecture of the source drive IC used in the TFT LCD is proposed. A new linear active resistor string DAC architecture is capable to support more size efficiency and multiple gamma value and reduction RC delay. It is implemented in 0.35 μm CMOS process, and INL & DNL of active resistor string DAC are ±0.5 LSB and ±0.3 LSB each other.
