ADC non-linearity correction based on INL(n) approximation - Experimental verification

Correction of ADC non-linearity can improve the accuracy of AD conversion. Except other possibilities the analytical inverse function of INL(n) curve can be applied. The first achieved result was published in [1]. Further simulations took into account also additive noise, jitter in sampling, non-zero sampled signal phase and hysteretic behavior of the ADC. The result of these simulations was published in [2]. Evaluation of the method using real data of several different AD modules is introduced in this paper.
