Welcome

The Designer's Guide Community

The Designer's Guide® Community website is a place where analog, mixed-signal and RF circuit designers come to learn about simulation, modeling and design. There are a number of very practical papers on simulation and modeling on the Analysis, Modeling, and Theory pages. A collection of useful example models can be found on the Verilog-AMS page. Papers on design methodology can be found on the Design page. And finally, our most popular feature is the Forum, where designers gather to share information about the challenges they face.

The Designer's Guide Community is built around the contributions of its members. Most chose to contribute through discussions on the Forum, but some go so far as to write and contribute either papers or models. So if you have some special knowledge you would like to share, or if some useful and well-written models, please consider submitting them.

What's New

October 2020 — Flicker Noise Model

A paper on writing flicker noise models that are compatible with RF simulation is now available. Flicker Noise Formulations in Compact Models by Geoffrey Coram, et al has been published in IEEE Transactions on CAD, vol. 39, no. 10, October 2020.

Resistor models that demonstrate the problem and the fix are available in a GitHub repository. Also included is a circuit that shows the problem in the BSIM model. The repository includes scripts that allow you to easily run the simulations yourselves.

You should read this article if you are concerned about the accuracy of your RF noise simulations or simply want to understand a little more about flicker noise.

January 2020 — How PNoise Analysis Works

If you have ever wondered about the conceptual underpinnings of PNoise analysis and don't have the time to read the papers, you might want to take a look at this post.
