摘要

提出了一种采用电阻-电阻串DAC (RRDAC)的10b LCD列驱动器，其DNL和INL的LSB分别为0.24、0.37，与采用传统电阻串DAC的8b LCD列驱动器相比，其面积缩小了17.4%。为了解决以往RRDAC存在的功耗大、不适用于非线性伽马曲线等问题，我们提出了一种采用压降补偿粗解码器的RRDAC。

A low-area 10b column driver with resistor-resistor-string DAC for mobile active-matrix LCDs

A 10b LCD column driver with resistor-resistor string DAC (RRDAC) is proposed having 0.24, 0.37 LSB of DNL and INL, and 17.4% of area shrinkage compared with an 8b LCD column driver with traditional resistor string DACs. To resolve the problems of the previous RRDACs such as power consumption increase, and inapplicability for nonlinear gamma curve, we propose an RRDAC using voltage-drop compensated coarse decoders.
