A non-linear dynamic S/H-ADC device model based on a modified Volterra series: identification procedure and commercial CAD tool implementation

A non-linear dynamic empirical model, based on a Volterra-like approach, was previously proposed by authors for the time-oriented characterization of S/H-ADC devices. In this paper, the experimental procedure for model parameter measurement is presented, as well as techniques devoted to the implementation of the model in the framework of main commercial CAD tools for circuit analysis and design. The results of simulations, performed on the obtained model both in time and frequency domain, are proposed which show model capability to point out the dynamic non-linear effects in the device response.
