dc.description.abstractThis paper presents a 10-bit column driver IC for active-matrix LCDs, with a proposed iterative charge-sharing based (ICSB) capacitor-string that interpolates two output voltages from a resistor-string DAC. Iterative mode change between a capacitive voltage division mode and a charge sharing mode in the ICSB capacitor-string interpolation suppresses the effect of mismatches between capacitors and that of parasitic capacitances; thus, a highly linear capacitor sub-DAC is realized. In addition, the area-sharing layout technique, which stacks the interpolation capacitor-string on top of the R-DAC area, reduces the driver channel size and extends the bit resolution of the gamma-corrected nonlinear main R-DAC. Consequently, the proposed ICSB capacitor-string interpolation scheme provides highly uniform channel performance by passively dividing the coarse voltages from the global resistor-string DAC with high area efficiency, and more effective bit resolution for nonlinear gamma correction. The prototype column driver IC was implemented using a 0.11-mu m CMOS process. The area occupation of the DAC and buffer amplifier per channel is only 188 x 15 mu m(2), and the static power consumption is 0.9 mu A/channel with no additional static power dissipation for the interpolation. The measured maximum DNL and INL are 0.25 LSB and 0.43 LSB, respectively. The measured maximum inter-channel DVO is 5.6 mV. The proposed chip achieves state-of-the-art performance in terms of chip size and channel-to-channel uniformity.-
