Abstract
A method and apparatus for a digitally-corrected analog-to-digital converter (ADC) are disclosed. The apparatus comprises a nonlinearity generator that generates one or more nonlinear characteristics of a time varying input signal and that causes unwanted signal components at frequencies other than a frequency of the time varying input signal, a frequency response modifier coupled to the nonlinearity generator that modifies the unwanted signal components by altering an amplitude of the unwanted signal components, a frequency response compensator coupled to the frequency response modifier, wherein the frequency response compensator compensates for the modification introduced by the frequency response modifier to provide a filtered digital signal, and an inverse nonlinearity generator coupled to the frequency response compensator for receiving the filtered digital signal, wherein the inverse nonlinearity generator compensates for the one or more nonlinear characteristics.
