Abstract
A generic nonideal behavioral model of A/D converters that can be characterized from published specifications is described. Three conversion methods (successive approximation, flash, and dual-slope) are modeled. A/D converter architecture may be changed by simple specification of external parameters. The model has been implemented in a mixed mode simulator and simulation results are provided. As an example, characterization has been done for the ADC574A manufactured by Burr-Brown. This is a 12-b A/D converter using the successive approximation method. This behavioral model is characterizable from manufacturers´ data sheets, is flexible, provides accurate modeling of nonideal behavior, and has a high simulation speed
