Editors' NotesVolume 40, Number 3, 2006


You may have noticed that the time span of our Web archive has been growing. As these words are being penned (all right, keyed!) the list of complete back issues in PDF goes back to Volume 11 (1977). By the end of the current year (2006), our 40th consecutive year in print, the roll call will be complete, starting with

Volume 1, Number 1 (1967), and our weary scanner (and its wearier operator) can rest.

What does it all mean? First of all, the world will have available a journalistic history of products, technologies, and applications Analog Devices has been involved in, including our many successes—and yes, the few egregious failures otherwise lost in the mists of history.

Second, you will meet many of the (by now, several generations of) engineers who were part of this stream, including (perhaps too much of) ourselves—and so will get a flavor of the times.

A few cautions are necessary: These pages are reproduced without further editing, and may contain inaccuracies, especially in light of the passage of time. Since many (perhaps most) of the products mentioned, especially in the earliest days, are obsolete and perhaps long forgotten, even by us, the words you read in our pages may be the only surviving record of their existence. Your expectations of obtaining further information from us should properly be low.

Looking back at sampled pages, we’re again impressed at their readability, but we also note that, even with the high-resolution scanning, the detail in some of the illustrations is inevitably lost. The interested reader may have to tap one’s own creativity to guess at the details. Finally, because the scanning technique does not recognize characters, sufficient information has not been available to conveniently assemble a helpful index the easy way.

So with these caveats, we invite the historically interested reader to plunge into this literary stream and sample our global flow of signal processing products, technologies, and applications, as viewed from Norwood, Massachusetts.


Frederic Boutaud, an ADI Senior Engineer, has been named to the distinguished position of Fellow during the Company’s 2006 General Technical Conference (GTC), which attracted more than 1500 engineers from our design sites worldwide.

The Fellows honor is bestowed on a select group of engineers whose innovation, leadership, entrepreneurialism, and consultative skills have contributed

significantly to ADI’s business success. In addition, “an ADI Fellow must be a Company ambassador, bridging across organizations and demonstrating an unparalleled ability to teach and mentor others within the Company,” noted Sam Fuller, Vice President of Research and Development.

With his induction, Boutaud, who has amassed an impressive 46 patents in the CPU and wireless processing fields, brings to 31 the number of Fellows at the top of the technical ladder among the Company’s 3,000 or so engineers worldwide.

A 25-year veteran in the field of digital IC design and architecture, Boutaud joined ADI in 1996 and assumed project lead responsibility for the digital baseband IC team, which designed the Softfone® architecture for GSM baseband processors, “one of ADI’s largest and most complex system-on-a-chip designs at the time,” said Fuller. “Frederic was the IC leader, as part of the core team—from system engineering, algorithm engineering, and IC engineering disciplines—who drove architecture- and product innovation to realize this highly innovative, scalable wireless architecture.”

“Frederic has been a key leader of the RF and Wireless business unit’s system-on-a-chip efforts and champion for SOC design at ADI. His technical leadership and design innovations in digital ICs have contributed to ADI’s accomplishments in wireless; and our analog design teams received a greater exposure to system IC techniques through his work.”

Prior to joining ADI, Boutaud was an IC design engineer at Texas Instruments, where he worked with a wide range of technologies, including CPU design, oversampling converters, graphic and video processing, and low-power DSP core design. Born in Meudon (France), he was graduated from École Centrale de Lyon in 1978 with an MSEE degree. He lives in Waltham, Massachusetts. His spare-time activities include music, yoga and biking.

We love hearing from you, our faithful readers, and invite your comments on anything from the quality of our articles to the layout of our publications to the content of these editorials. Those of you who read Analog Dialogue online may already have noticed the new feedback box at the end of each recent article. In each box, you will find a link to Analog Diablog (http://analogdiablog.blogspot.com), where we encourage you to open a dialogue with the authors and your fellow readers. Or, as always, please feel free to send email directly to the authors, or to us, your attentive editors. As a token of our appreciation, we’ll send a limited-edition 40th-anniversary pint glass to those readers who send the best suggestions for improving Analog Dialogue.


While reading about Blackfin processors in RFID readers, many of you may have realized that this is the same technology that you use every day to open doors with your company ID badge, buy groceries with your MasterCard PayPass, or pay at the pump with your Mobil Speedpass. In the age of identity theft, many of you may be concerned about the confidentiality of your personal information. Smart cards contain the same information that is encoded on the magnetic strip of a conventional credit card, but they are much more secure. Unlike magnetic strips, which can be cloned with a $20 reader—following easy-to-find instructions—smart cards allow different pieces of data to be kept distinct, where they can only be accessed by relevant applications. They use various levels of encryption and authentication, and can be combined with biometrics or keypads for additional security. The card never leaves your possession, providing additional safety and speed. More information on contactless smart-card technology, payment options, and privacy concerns can be found at http://www.ieprox.com/epayment_white_papers_payment.asp.
