Abstract

The increasing complexity o f data converter architectures m akes it necessary to use behavioral m odels 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. A iming at this objective, this paper analyses the m ost utilized a rchitectures and identifies the basic (active and passive) building blocks used. Behavioral m odels o f such basic blocks are discussed. The proposed behavioral m odels 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 b locks specification that permit to m et given data converter requirements.
