In the process of measuring the ADC test chip's performance, I wrote some MATLAB scripts to generate the FFT, INL, and DNL plots and compute the ENOB. While the techniques used in the scripts are very common knowledge, I am posting them as a reference for anyone interested in ADCs. Please inform me if you become aware of errors in the scripts.
  1. calcfft.m: Computes the DFT spectrum for a real signal. Uses the Hann window. Sums up smeared bin power to determine SNDR. Test code generates a pure sinusoid quantized to N-bits.
  2. histdnlcalc.m: Computes the DNL based on the sinusoid histogram testing method (Doernberg, Lee, and Hodges, JSSC 1984). Test code generates a highly-oversampled sinusoid with a missing code.
