ANALOG AMPLIFIER AND METHOD FOR DRIVING OF THE SAME AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME

摘要

An analog amplifier, a driving method thereof, and a liquid crystal display device are provided to obtain an output voltage to an input voltage with a required voltage ratio by controlling a resistance value and a capacitor value. An input signal is applied to a positive terminal of a comparator(30). A feedback voltage is applied to a negative terminal of the comparator. A first reset reverse signal switch(rstb1) is equipped between the comparator and an output terminal. The first and second capacitors are connected between the output terminal and a ground terminal of the comparator in parallel and distribute the voltage. A second reset reverse signal switch(rstb2) is equipped in a node between the positive terminal of the comparator and the first and second capacitors. The reset signal switch is equipped between an output terminal and the ground terminal of the comparator.
