High-level continuous-time sigma delta design in Matlab/Simulink

This paper presents a framework for behavioral simulations of continuous time delta-sigma modulators (CTSD) developed in Matlab/Simulink. Error sources in CTSD designs are reviewed and it is explained how sub-module specifications can be derived from a system-level target performance. The paper also...

Zusammenfassung:This paper presents a framework for behavioral simulations of continuous time delta-sigma modulators (CTSD) developed in Matlab/Simulink. Error sources in CTSD designs are reviewed and it is explained how sub-module specifications can be derived from a system-level target performance. The paper also discusses considerations of importance when using Simulink for CTSD modelling, like the choice of solver and simulation speed optimization. An example CTSD design is used throughout to illustrate the results and error models.
