A Guide to Simulation & Modeling for Analog & RF Circuit Designers

The Designer's Guide® Community website is a site 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. A list of recommended reference books for analog & RF designers is given in Books. 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.

Featured Material
Designer's Guide Consulting has created, a site that you can use as a detailed quick reference guide for Verilog, Verilog-A, Verilog-AMS. The reference material is not complete at this point, but is still quite usable. Over time the reference material should fill out and be supplemented with useful application notes and annotated models that will help you learn how to use Verilog-A/MS more effectively. We aim to make your everyday source for information on Verilog-AMS. Please take a look.
BMAS Archives
The Designer's Guide Community is now hosting the BMAS Archives. BMAS was a conference dedicated to Behavioral Modeling and Simulation. It ceased operations a few years ago, but the archives hold a great deal of useful information about the subject.
Linux Utilities
As a heavy user of Linux I have written my share of utilities through the years. Some have proven to be so unique and useful that I have gone to the trouble of packaging them up for general use. You can find these at my hobby site, Of particular note are Avendesora, a powerful collaborative password generator, FVI, a useful combination of grep and vi, EC, my engineering calculator, svg_schematic, a package for creating SVG schematics that are useful for documentation and presentations, and QuantiPhy, a package for reading and writing numbers that employ SI scale factors. I encourage you to try them out, and send me an email if you do. I'd like to know if you are using them, and why you chose not to if you do try them.
New Downloadable Engineering Calculator
If you like the web-based calculator on this site and would like something similar to download and run on your own computer, visit Nurdletech and download ec. It is similar to the Designer's Guide calculator in that it is an RPN calculator that support SI scale factors, but it operates purely from the command-line.
Engineering Fundamentals
I have written a collection of papers on electrical engineering fundamentals that are intended to be a source of useful introductory information to engineering students. Currently their are papers on Fourier series, phasors, ideal opamps and feedback, and bipolar transistors.
Modeling Data Converters
A comprehensive paper on modeling data converters with Verilog-AMS from Monte Mar.
BER of Bang-Bang CDRs
A paper that presents a methodology for predicting bit-error rate of bang-bang clock and data recovery circuits.
Verilog-AMS 2.4 Released
The latest version of the Verilog-AMS LRM has been released and is available.
New Boards on Forum
We have added three new boards to our Forum. The boards cover analog verification and mixed-technology design.
Engineering Web Calculator
The Designer's Guide Community is currently trying out an online calculator that is specifically designed for analog designers. It is an RPN calculator that provides operations and constants useful to circuit designers. In addition it has several unique features that serve to distinguish it from other scientific calculators available on the web:
1. Efficient command line entry.
2. Entry and display of numbers with SI scale factors.
3. Entry and display of integers in base 2, 8, 10, and 16 using Verilog format.
4. Multistep undo.
5. Compatibility with your computer's clipboard or copy & paste feature.
6. Observable memories.

Learn more about it by visiting its help page. Let me know what you think of it, or tell me of any ways you think it can be improved.
