One embodiment of the invention is directed to a method comprising an act of performing digital correction of an offset in a system comprising an analog-to-digital converter (ADC) having a usable input range that is greater than a nominal input range, wherein the offset exists at an input of the ADC. Another embodiment of the invention is directed to a system comprising an ADC having a usable input range that is greater than a nominal input range, wherein an offset exists at an input of the ADC and the offset is corrected using digital correction.
