dc.description.abstract | We propose a high-speed rail-to-rail 10-bit
column driver with a reduced die area for LCD-TV applications. This column driver combines an 8-bit resistorstring digital-to-analog converter (R-DAC), constructed using a hybrid-type decoder to reduce the RC time delay and die area, with a 2-bit interpolation DAC. In the output buffer, error amplifiers drive a column line so as to realize a highspeed rail-to-rail drive. Gamma-corrected output voltages are generated by the resistor string of R-DAC, which contains resistors of unequal values that match the inverse of the liquid crystal transmittance-voltage characteristic. A prototype 10- bit LCD column driver was designed and fabricated using a 0.3μm CMOS technology, and has a settling time of within 2μs and a quiescent current of 5.4μA per channel. | en |
