Abstract
A method for converting a sampled analog signal into digital is provided. An input signal is sampled at a sampling instant to generate a sample voltage. A first current is then applied to a node to change a voltage on the node, and a first interval to change the voltage on the node to a reference voltage from the sample voltage using the first current is determined. A second current is then applied to the node to change a voltage on the node prior to a subsequent sampling instant, and a determination of a second interval to change the voltage on the node to the reference voltage from the sample voltage using the second current is made.
