ABSTRACT:
A nonlinearity detection system for an analog to digital converter (ADC) comprises a signal generator that generates a periodic signal that is output to the ADC and that comprises first and second intervals. The periodic signal monotonically increases during the first interval and monotonically decreases during the second interval. A differentiator module communicates with the ADC and that generates an output signal that is based on an output of the ADC and a delayed output of the ADC. A nonlinearity detection module detects slope discontinuities in the output signal of the differentiator module.
