Abstract

See full text

Circuitry for correcting non-linearity of an analog-to-digital converter. A non-linearity correction system for an analog-to-digital converter (ADC) includes coefficient storage, coefficient transformation circuitry, and correction circuitry. The coefficient storage is encoded with a first set of coefficients for correcting non-linearity of the ADC at a first sampling rate. The coefficient transformation circuitry is coupled to the coefficient storage. The coefficient transformation circuitry is configured to generate a second set of coefficients for correcting non-linearity of the ADC at a different sampling rate. The correction circuitry is configured to apply the second set of coefficients to correct non-linearity in output of the ADC while the ADC is operating at the different sampling rate.
