BEHAVIORAL MODELING AND SIMULATIONS OF DATA CONVERTERS

摘要

The increasing complexity of data converter architectures makes it necessary to use behavioral models to simulate the electrical performances and to determine the relevant data converter features. For this purpose, special input stimulus and specific output data processing are required. Thus, we need a specific data-converter simulation environment. Aiming at this objective, this paper analyses the most utilized architectures and identifies the basic (active and passive) building blocks used. Behavioral models of such basic blocks are discussed. The proposed behavioral models are then used in a pipeline and a sigma-delta converter. Specific routines for the determination of data converter parameters are presented. Simulations show that in addition to the analysis of limits and the electrical features extraction designer can determine the basic blocks specification that permit to met given data converter requirements.
