DYNAMIC BEHAVIOR MODELS OF ANALOG TO DIGITAL CONVERTERS AIMED FOR POST-CORRECTION IN WIDEBAND APPLICATIONS

• Abstract:

  In this paper a dynamic behavior model of analog to digital converters is proposed. The model is aimed for post correction in wideband applications. The suggested post correction method is a combination of look up tables and model based correction.
  The model consists of three components. The first is a component represented by a Hammerstein model; that is a static nonlinearity followed by a time invariant linear filter. The second component is a nonparametric model caused by significant deviation from the characterized integral nonlinearity and the output from the Hammerstein model. The third component contains of the remaining deviation and is considered as a random model error.
  Results from simulations verify that the examined ADC can be described by an ordinary Hammerstein model and a static look-up table.
