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.
It may not look it but this website has been completely rebuilt to make it easier to maintain. This should not matter too much to you, except the site should look cleaner as all the out-of-date material has been removed.
Please let me know if you experience any difficulties with the updated site.
The paper on hidden state was updated to include more models and to add a section on small-signal propagation.
