Název v původním jazyce

Several Approaches to ADC Transfer Function Approximation and their Application for ADC Non-Linearity Correction

Popis výsledku v původním jazyce

The performance of current electronic devices is mostly limited by analog front-end and analog-to-digital converter's (ADC) actual parameters. One of the most important parameters is ADC nonlinearity. The correction of this imperfection can be accomplished in the output data but only if the nonlinearity is well characterized. Many approaches to ADC characterization have been proposed in scientific articles in the last several years. In this paper three different approximations of ADC low-frequency non-linearity (common polynomials, Chebyshev polynomials and Fourier series) were analyzed and the practical applicability, approximation accuracy and noise sensitivity were investigated. The first results of nonlinearity correction were presented, too.
