Editorís Notes

Dan Sheingold We are pleased to note the introduction of 3 new Fellows at our 1998 General Technical Conference: Roy Gosser, Bill Hunt, and Chris Mangelsdorf. Fellow, at Analog Devices, represents the highest level of achievement that a technical contributor can achieve, on a par with Vice President. The criteria for promotion to Fellow are very demanding. Fellows will have earned universal respect and recognition from the technical community for unusual talent and identifiable innovation at the state of the art; their creative technical contributions in product or process technology will have led to commercial success with a major impact on the company's net revenues.

Attributes include roles as mentor, consultant, entrepreneur, organizational bridge, teacher, and ambassador. Fellows must also be effective leaders and members of teams and in perceiving customer needs. This trio's technical abilities, accomplishments, and personal qualities well-qualify them to join Derek Bowers (1991), Paul Brokaw (1980), Lew Counts (1984), Barrie Gilbert (1980) Jody Lapham (1988), Fred Mapplebeck (1989), Jack Memishian (1980), Doug Mercer (1995), Mohammad Nasser (1993), Wyn Palmer (1991), Carl Roberts (1992), Paul Ruggerio (1994), Brad Scharf (1993), Mike Timko (1982), Mike Tuthill (1988), Jim Wilson (1993), and Scott Wurcer (1996) as Fellows.

Royal A. Gosser is an innovator whose design track record is highlighted by products labeled "First", "Fastest", and "Greatest SFDR". A perennial contributor of new ideas, Roy has designed products that include various A/D converters, op amps, and track and holds. Recent well-known products include the AD9042A/D converter (co-designed with Frank Murden), the AD8011 op amp, and the AD8320 cable line driver. He holds 4 patents.

Equally as important as creative circuit design, a key to IC device performance is the manufacturing process. Roy has supplied ideas and other inputs to assist our process engineers in designing the Analog Devices XFCB (eXtra-Fast Complementary Bipolar) process, one that makes possible the manufacture of some of the world's highest-performance analog ICs in silicon.

Roy joined Analog Devices Computer Labs Division, in Greensboro, NC, in 1982 as an IC design engineer, meeting the challenge to build better interstage amplifiers for A/D converter cards. After a 4-year interlude as Manager of Product Test Engineering, he returned to the design of integrated circuits--and hasn't looked back! Before joining ADI, he had worked in R/D at Litronix (now Siemens), as a design engineer at Hewlett Packard (Palo Alto), and then at Harris Semiconductor. His training included 4 years with Naval Air as an electronic technician, followed by a BSEE from San Jose (CA) University and an MSEE from National Technological University (NTU).

Since 1983 Bill has been Design Engineering Manager at ADI's site in Limerick, Ireland. During this time Bill has continually contributed designs and leadership to many core developments, in D/A and A/D converters of all types, including sigma-delta. He has been chief proponent and architect of devices in the servo section of hard-disk drives (HDD). He led the design of baseband audio converters for digital wireless telephony and products for basestations and wired telephony. He also developed a line of DDS products.

He has shown a great ability to understand customer system problems and to develop solutions in terms of new directions for semiconductor technology. He has been active in developing computer-aided design techniques, providing inputs to process-technology developments and measurement techniques.

Bill graduated with a BSEE in 1967 and worked his way through the development engineering ranks of Telectron Ltd, a telecommunications equipment manufacturing company, before joining Analog Devices in 1979 as a Design Engineer. During this period, he gained insight into the emerging infrastructure of the telecom industry and their inherent dependence on early adoption of semiconductor technology as a competitive advantage.

Dr. Christopher W. Mangelsdorf designed the AD770 8-bit, 200-MSPS A/D converter, and went on to lead a team that designed the industry's first CMOS 10-bit, 15-MSPS ADC and the first high-resolution integrated CCD signal processing chip for digital cameras. These have served as core designs for many other CMOS high-performance products. For the last 2 years, Chris has managed the product design center that serves our customers in Japan.

Chris represents ADI on the Bipolar Circuits and ISSCC conference committees; he has chaired panels and presented papers at these and other conferences. He has published >10 technical papers and has 13 patents (5 shared). He serves as a link to college campuses and as a mentor to young team members.

He received a BS in Physics from Davidson College (NC) in 1977, and went on to earn a Master's degree, then a Ph.D., in Electrical Engineering at MIT, where he held the Analog Devices Fellowship. He has been associated with Analog Devices since summer employment in 1980. He enjoys board sports, i.e., windsurfing, surfing, and snowboarding.

Last December, at 72, Frank Goodenough finally succumbed after a long and courageous fight against cancer. At the time, he was Electronic Design's Analog and Power Technology Editor. For nearly two decades, he reported to Electronic Design's readers on just about everything new and important in analog circuit progress. In the two to three years just before he joined ED, we had the good fortune to get to know Frank as a colleague at Analog Devices and a regular contributor to these pages. We knew him to be articulate, fearless, innovative, enthusiastic, lively, and intellectually omnivorous. He had a hunger for new ideas, and a passion to find new ways to apply them. With Frank, there was always something interesting to talk about, never a dull moment.

We were fortunate that his new calling, as an ED editor, kept him in touch with us, and we were glad to see him on his occasional visits to our facility. His colleague at Electronic Design, Roger Allan, wrote a beautiful farewell tribute (March 9, 1998 issue) so accurate that reading it virtually brings him to life in our minds. We were glad to have known him and to have had a part in the preparation for his ED career--the culmination of the colorful and varied panoply of experiences that shaped a truly unique person.
