ADC Compensation Using a Sinewave Histogram Method

of the Thesis Presented in Partial Fulfillment of the Requirements for the Degree of Master of Science (in Electrical Engineering) Aug. 1997 This thesis describes a new method for developing ADC error function models using standard sinewave histogram methods. The histograms supply information to accurately estimate expected error for each ADC output code. The method provides better error representation by providing error basis functions for every output code. Results show this method is capable of removing all slope dependent errors in complex ADC error models and application to a 200 MSPS ADC showed more than 10 dB improvement in SFDR over the full nyquist band for the ADC.
