Abstract:
A system for displaying images is provided. A capacitor type digital-to-analog converter is coupled between a first node and a second node and generates a first analog signal according to a digital signal with N bit data. An analogue buffer is coupled between the second node and a third node and generates a second analog signal according to the first analog signal and a bias voltage. A first switch is coupled between a predetermined voltage and the second node. A second switch is coupled between the first node and the third node.
