Abstract
A ramp generator includes a digital-to-analog converter, a first capacitor, a second capacitor and a noise cancellation circuit. The digital-to-analog converter is configured to generate a ramp-up voltage signal on a first output terminal and a ramp-down voltage signal on a second output terminal. The first capacitor is coupled between the first output terminal and an intermediate node. The second capacitor is coupled between the second output terminal and the intermediate node. The noise cancellation circuit is coupled with the intermediate node. The noise cancellation circuit is configured to provide a compensation feedback according to an intermediate voltage on the intermediate node.
