Abstract
The Capacitor DAC with gamma correction is proposed for TFT-LCD (Liquid Crystal Display) driver application. It is based on two ideas. First, 6bit digital code is converted 8bit digital code by memory circuit (Look Up Table) for gamma correction. second, weighted voltage ratio DAC is proposed for reducing area and power consumption.
