摘要：

One of the most important parameter of ADC which negatively influence its quality is its nonlinearity. The correction of this imperfection can be accomplished in the output data but only if the nonlinearity is well characterized. Two methods - application of look-up table or an analytical inverse function of INL(n) curve - from other possibilities can be used for the ADC nonlinearity correction. The first results of correction using look-up table were published in [5]. The application of inverse function, which is dependent on the possibility to derive the inverse function to the function approximating the INL(n) curve, is published in the paper.
