Analysis of the conversion function nonlinearity of the analog-digital converter




conversion function, analog-digital converter, integral nonlinearity (INL), differential nonlinearity (DNL), dynamic characteristics of ADC


The study aims to analyze analog-to-digital converter (ADC) nonlinearity in digital measuring instruments such as oscilloscopes, multimeters, and spectrum analyzers. The non-linearity of the ADC can lead to insufficient accuracy, distortion and inhomogeneity of the signal transformation. The research examines the factors that cause the nonlinearity of the ADC and the methods of evaluating its influence on the measurement results. Also considered are the parameters related to the nonlinearity of the ADC, which are standardized in the technical descriptions, allowing to assess the level of nonlinearity and make appropriate corrections during data processing.
