Abstract
This paper proposes a 9b quasi-pipeline DACs and column multiplex techniques for small-format LCD column drivers. The DAC provides uniform channel performance, built-in gamma correction through nonlinear global resistor string values, and occupies a smaller column driver size. The maximum DNL and INL were measured as 0.25 LSB and 0.33 LSB, respectively. The averaged data conversion time is 16 ns per channel. The FoM of the proposed DAC is 0.2 pJ/bit/mm2, which is smaller than that of prior arts.
