Abstract
We propose a behavior-based macro-model of mixed ADC systems as a tool for high-level simulation, investigation and pilot testing, as well as a tool to facilitate and support a design process of other systems containing them. Our aim is to characterize the dynamic and nonlinear properties of ADC systems simultaneously with the representing of discrete nature of ADC output. To introduce the model, we assume that nonlinear and dynamic properties of the system can be separated. Decomposition of the nonlinear static characteristic is performed to calculate the output signal for any sinusoidal input signal. To deal with dynamics, traditional coefficients of the differential equation input-output are used. The discrete nature of ADC system is taken into account by an ideal quatizator, operating at the output of the model. As a result, behavior of the system can be described with a small set of parameters, and each of them can be estimated experimentally. The simulation results confirmed the usefulness of the model.
