NON-LINEAR MODEL BASED CALIBRATION OF D/A CONVERTERS

• Abstract:

  Various error sources cause linearity errors which degrade the performance of D/A converters. The paper presents a non-linear model to describe multiplying D/A converters. A Walsh transformation based diagnostic tool is used to determine the model parameters. Based on this model, a calibration scheme is derived, in order to compensate the non-linear behaviour of the converter. Practical applicability of the proposed method is shown by measurements performed on a custom designed test circuit.
