“…One of critical requirements is to make digital-to-analog converter (DAC) smaller without performance degradation. Various DAC schemes such as cyclic DAC [1], resistor-resistor DAC [2], interpolation-type DAC [3], and hybrid resistor-capacitor DAC [4], has been developed to achieve this goal. In this paper, a 12-bit segmented resistorcapacitor (R-C) DAC with smaller area is introduced along with its application to the source driver.…”

“…However, the area of R‐DAC and its related routing lines are prohibitively large for a high‐resolution data converter. So, various combinations of R‐DAC and interpolation have been proposed to achieve both high area‐efficient design and high resolution performance . As the number of interpolation bit increases, metal routings of decoder can be reduced.…”

-A universal column driver is implemented in a 0.13-μm high-voltage CMOS process for not only TFT-LCD but also OLED applications. The proposed column driver employs 13-bit linear DAC to cover all gamma curves of display applications and address-based configuration for intra-panel interface protocol to support both TV and IT applications. Measured results demonstrate the average voltage of output channels (AVO) is under 1mv, which satisfies 1-LSB resolution at 18.5V of AVDD.

Abstract— A 12‐bit segmented R‐C DAC to support a linear gamma curve has been proposed and fabricated in a 720‐channel LCD source driver with a 16‐V 1‐poly 3‐metal high‐voltage CMOS process. The proposed DAC has a global resistor string and sample‐and‐hold buffers. A MSB voltage selected by the upper 6 bits of input data and a LSB voltage selected by the lower 6 bits of input data are summed by using a sample‐and‐hold operation with offset cancellation in the proposed DAC. The measured DNL was less than 0.3 LSB, and the output voltage deviation was less than 3 mV in all gray levels. Although two sample‐and‐hold buffers were adopted to operate alternatively, the die size was as small as 24.9 mm2, which was only an 8.3% increase compared to that of a conventional 8‐bit 720‐channel source driver. Because of its good performance with small area, the proposed DAC can be a good low‐cost solution for a 10‐bit TV system.
