- Abstract
We adopt a novel digital-to-analog conversion (DAC) architecture entitled 'quarternary-type DAC (Q-DAC)' to column drivers for active-matrix displays. To realize the Q-DAC architecture, we newly design level-shifters and decoders. Compared with conventional binary-type DAC, our Q-DAC is more area-efficient and has smaller RC-delay characteristics. Proposed circuit has been verified by sucessful fabrication of a 6-bit column driver for active-matrix liquid-crystal displays (AMLCDs). The area of DAC block has been reduced up to 30%. The number of gross-die per wafer has increased about 10% and the output delay has been reduced 200 ns to 100 ns
