[Show abstract][Hide abstract] ABSTRACT: A 10-bit folded multi-LSB decided resistor string DAC is presented. The proposed circuits uses the LSBs of the input digital words to decide the output voltage, which can significantly reduce the number of unit resistors up to 75% compared with the traditional resistor string DAC. The measured results show that the INL is less than 0.73 LSB and the maximum DNL is 0.26 LSB. The active chip area is less than 0.25 mm<sup>2</sup>
[Show abstract][Hide abstract] ABSTRACT: A novel Gamma Voltage Control (GVC) technique that can increase the color depth of TFT LCD has been developed. With this method, we can use n bit data driver to provide more than n bit performance on the display. Experimental results successfully demonstrate the feasibility of this method.
