Refunds

All sales are final and non-refundable, except where required by applicable law or the Paddle Refund Policy. For digital software delivered immediately, applicable withdrawal rights may end once downloading or use begins, where permitted by law and with the buyer’s express consent. Refund requests for Paddle transactions must be submitted through Paddle’s buyer support channels.

Check compatibility before purchasing

The MATLAB App requires MATLAB R2022b or newer and a compatible, separately licensed Delta-Sigma Toolbox. It is not a standalone executable.

The CIFF model requires a compatible, separately licensed Cadence Virtuoso/Spectre environment; it does not include the App or a complete incremental ADC. See its package and setup requirements.

The incremental MATLAB model collection requires MATLAB and Statistics and Machine Learning Toolbox for its existing random-number code, or adaptation to equivalent functions. See its setup requirements.

Read the App installation requirements, terms and conditions, and license notice before purchasing.
