STATIC AND DYNAMIC A/D CONVERTER NONLINEARITY
Abstract
The ADC’s static and dynamic nonlinearity with relation to harmonic distortion and parameters describing the nonlinearity are discussed. The commonly used description by INL and hysteresis is acceptable only if the dynamic nonlinearity is significantly lower than the static nonlinearity. The significance of dynamic nonlinearity is presented on the measurement and the analysis based on complex spectrum is demonstrated. We call the attention to more detailed tests of ADC according to the dynamic nonlinearity and definition of an optimal working point with maximal SFDR.
