Post-Correction of ADC Non-Linearity Using Integral Non-Linearity Curve

Original language description

The accuracy of AD conversion can be improved using the post-correction of digitizer non-linearity. In principle two methods could be applied ? look-up table or an analytical inverse function of integral non-linearity curve (INL(n)). Look-up table can beeasily implemented but it demands huge memory space particularly for high resolution ADCs. Inverse function offers flexible solution for parameterization (e.g. frequency dependence) but it also requires fast DSP for real-time correction. The data or coefficients for both methods are frequently determined from a histogram of acquired pure sinusoidal signal. Non-linearity curve can also be gained by another procedure demanding significantly less samples ? approximation from a frequency spectrum. The correction of ADC nonlinearity by means of inverse function of INL(n) curve is analyzed in this paper and the results are presented.
