A GUI driven Σ-Δ modulator design, evaluation and measurement tool with a view to practical implementation

A user-friendly design tool created in the MATLAB/Simulink environment to speed up the design, analysis, evaluation and measurement of single-loop and multistage sigma-delta (Σ-Δ) modulators at the system level is presented in this paper. The tool covers a variety of Simulink-based design topologies of low-pass, band-pass and high-pass Σ-Δ modulators.
