摘要：
A major challenge for mixed signal circuit design is to solve the contradiction between system simulation time and accuracy for the real non-ideal effects. Sigma-Delta modulator is such a kind of circuit that is very popular in signal processing and communication systems nowadays. Its behavioral model is constructed and analyze of non-idealities are included in this paper. Almost all the non-idealities are applied into the proposed wide band architecture, which is not mentioned before. The model and simulation system is built in MATLAB SIMULINK platform and the simulation results are presented. The proposed model attains a better accuracy than existing work, while maintaining the fast simulation speed and flexibility for model reuse, which greatly improves the design efficiency.
