One of the most common questions I receive as an EMC consultant have to do with PC board design. And, no wonder. As clock and data frequencies increase towards 10 GHz, proper PC board design becomes an imperative for proper functioning of the system. The typical “rules of thumb” we used for low frequency boards no longer seem to apply.
So, when I ran across Lee Ritchey’s self-published book, Right The First Time – A Practical Handbook on High Speed PCB and System Design (Volume 1), I was intrigued. Both this book and the follow-on volume 2 (Advanced Topics) are available on his web site. Volume 1 is now out of print, but available separately as a 295 page PDF file for just $25. However, both volumes may be purchased for the special price of $95 (the price of volume 2, alone) – a deal I highly recommend. I’ll be reviewing volume 2 later. More…
I recently published a review of the following book in EE Times.
One of the most popular versions of SPICE today is Linear Technology’s LTSpice IV. This free and full-featured SPICE modeling software runs on PCs and includes schematic entry, great graphical plotting, and is very fast. While Linear Technology provides a basic on-line user guide, until now, there really hasn’t been a very comprehensive resource on using the software. Earlier this year, components supplier, Würth Electronik, alleviated this missing reference with their 700+ page book, The LTSPICE IV Simulator – Manual, Methods and Applications by author Gilles Brocard.
The software will run on either PC or Mac. To read more and add your comments, click here…

Many may not be aware, but Würth Electronics Midcom (WE Midcom) sells a monster 4-pound, 700-page book, the Trilogy of Magnetics, now in its 4th edition. The cost is 49 Euros or $49.99 USD, orderable through the WE Midcom web site or your local sales rep. This comprehensive design guide includes theory and applications for EMI filter, switch-mode power supply and RF circuit design. Now, many vendors supply application notes and white papers on their web sites or included with their catalogs, but usually, you need to wade through countless lists of products to find the meager theory and application information. While WE Midcom includes a few lists of ferrites in the book, the bulk of the content (99%) is packed with theory and applications. If you want the part information, that’s included on a CDROM in the back of the book. The CD also includes a copy of LTspice (from Linear Technology), plus a couple of WE selection/design programs.
The book, Trilogy of Magnetics, by Würth Electronics, is well worth adding to your reference library.
