  • Abstract:
    Experimental results are provided in this paper in order to validate the Discrete-Time Convolution approach, recently proposed for the modelling of both static and dynamic non-linearities in S/H-ADC devices. The comparison between actual device response and model predictions is provided, showing a very good agreement under operation conditions which are not suitably described by a conventional model, based on the characterisation of the static non-linearity only. A brief discussion about the possibility of embedding into the model almost any recent empirical technique for the characterisation of static sources of uncertainty within the device is proposed as well.
