Simple Evaluation of the Nonlinearity Signature of an ADC Using a Spectral Approach

Figure 4

(a) Typical averaged magnitude spectrum obtained from the AD C 1 output. It is used for the selection of the spectral lines taken as harmonics. (b) Comparison between two AD C 1 INL Histogram estimations: in thin (blue) line the one estimated with very few samples, (the four registers acquired to apply the new method). In thick (black) line the real INL.
