The Delta-Sigma Toolbox includes nearly 100 functions which support NTF synthesis, modulator simulation (from an NTF or a structure), realization, dynamic range scaling, SNR estimation and more. The toolbox is well-documented via the accompanying DSToolbox.pdf manual.
For further information regarding the Toolbox and Delta-Sigma modulators in general consider purchasing "Understanding Delta-Sigma Data Converters, Second Edition" by Pavan, Schreier and Temes (ISBN 978-1-119-25827-8).

Version Published Release Notes
2020.1

Corrected the "Required MathWorks Products" field in web listing

2020.0

Now includes functions to support the design of Polynomial-Based Filters: designPBF.m, frespPBF.m, impulsePBF.m, shiftPBF.m. Also updated ratapprox.m.

2016.1

Added demoLPandBP.m. Updated dsexample1.m and dsexample2.m

2016.0.0.0

Added designPBF.m (for designing polynomial-based filters using Hunter's method). Added dsexample*.m. Replaced simulateESL with simulateMS for simulating mismatch-shaping. Expanded dsdemo5.m (demonstration of mismatch shaping).
Actually uploaded the delsig.zip file this time.

1.3.0.0

Incorporated Jeffrey Gealow's improvements which remove restrictions on the tdac argument in realizeNTF_ct and mapCtoD. Values such as [1 3] or [2 3] are now OK.

1.2.0.0

Added functions for realizing an NTF with a continuous-time loop filter and for handling quadrature modulators.
