ABSTRACT:
An analog buffer used in a source driver is provided. The analog buffer havs an input end, an output end, a transistor, first and second capacitors, first, second, third, fourth and fifth switches. The source and the drain of the transistor is coupled to the output end and receives a first voltage respectively. The first end of the first and the second capacitors are coupled to the gate of the transistor. The second end of the first and the second capacitors are coupled to the first end of the first, second and fourth switches and the first end of the third and fifth switches respectively. The second end of the first switch receives a second voltage. The second end of the second and third switches are coupled to the input end. The second end of the fourth and fifth switches are coupled to the output end.
