摘要

The paper proposes a low area 10-bit DAC for AMOLED source driver ICs. The proposed driver consists of a 7-bit gamma correction resistor-string DAC and a 3-bit sub-DAC based on programmable current cell (PCC) within the output buffer. The output buffer with 3-bit sub-DAC could implement voltage interpolation with only two differential pairs and three CMOS switches. This leads to a compact die size. The AMOLED driver is realized in 0.35μm CMOS process with DNL and INL of 0.11 LSB and 0.15 LSB, respectively. The settling time within 0.2% tolerance of the final voltage is 3.7μs with a 30kω resistance and 20pF capacitance load.
