Abstract

The input/output relationship of a Sample/Hold and Analogue-to-Digital Conversion device (S/H-ADC) can be described as the response of a non-linear system with memory. A general-purpose “black-box” behavioural approach, based on a modified Volterra representation, has been proposed by authors for the modelling of a wide class of non-linear dynamic systems and specifically applied to the characterization of S/H-ADCs. In this paper, the instrumentation set-up and the experimental procedure for the extraction of S/H-ADC model parameters are presented and a novel standard for the characterization of non-linear dynamic effects in this family of measurement systems is proposed.
