The top ten analog engineers

January 26, 2009

PR megaforce Mark Alden over at National Semi tipped me off to an article in EETimes about the top 10 analog engineers. The article has a comment section but apparently you can’t even read the comments unless you register. So I figure I would post about the article here so we can all share our opinions without the obligatory WEB2.0 data-mining.

As to my opinion, well the first three picks are a little suspect, Philbrick and Solomon were businessmen that got their start in engineering. Maybe my pal Bob Pease can comment about Philbrick since he worked for them. No, I think to rank on the list of top engineers you should be working as one for most of your career. Even high-level folks like Monticelli and Gilbert, who are both fellows at their respective companies, have never gone over to the management side— they are hard-core technical. Then there is the whole issue of analog IC design vs. analog design. Analog IC designers are far more well known, since they are allowed and even encouraged to talk about their parts, since you really couldn’t copy them unless you have the same process and fab resources, as well as the design, simulation and layout tools. So we all know about Widlar, but what about all the analog geniuses that worked at Tektronix and Hewlett Packard and Picosecond Pulse Labs for that matter? They don’t publish all their stuff since keeping it secret is essential to staying in business, but we know they are pretty good. Just yesterday Jim Williams was telling me that all of us noticed how the analog engineers at HP were using diode-connected JFETs to get low leakage 20 years ago.

Now I’m not saying Philbrick and Gordon (who I never heard of) and Solomon should not be on the list. I think it is just digital and stupid to try and make a ranking. If you care about log amps and multipliers than Gilbert has to be number one, nobody has caught up to ADI in that sector. But there are a lot of other aspects to analog design, even above and beyond the whole IC/system-level thing. I have an affinity for wild men, so I probably would put Widlar at number one. If you want to see why go look at the datasheet for an LM10 (pdf). He designed it in 1977 and is still has world-class features and specs, even when he had to use a crappy process with no good PNP transistors. But I would not even know whom to pick for number two. Solomon was a great designer for conceptualizing the FET input op amp, but Dan Culmer did the actual IC design. And where is Rod Russell in the FET amplifier story? It was a process guy at National that figured out how to do JFETS that allowed Solomon and Culmer to do their thing in the first place. I already told you Williams would readily admit to studying the greats. Same for Pease, he also admits to standing on the shoulders of giants. The other thing that troubles me is who did not get mentioned. OK, so lets just look at analog IC designers. Where are Harvey, Erdi, Fulligar, Garth Wilson, Carl Nelson, Bowers, and the dozens of others that made great contributions? Where the heck is Frederiksen for crying out loud? Where are Lew Counts and JoAnn Close? Nello Sevastopoulos and the MF10? Where are my buddies Bill Gross and Don Sauer, who did the LM13600, a really remarkable part with an astounding applications section in the datasheet? Where is Camenzind and the 555 timer? And then lets look at the whole application crowd. Pease and Williams are surely cornerstones, but where is Walt Jung and Walt Kester from ADI? Where is Wild Bill Klein from TI not to mention Dave Freeman and Bonnie Baker? I still have my copy of the Linear and Interface Circuits Applications from TI, dated 1985. Where are the authors of that, Pippenger, Tobaben and McCollum? Don’t forget those great app notes form Unitrode back in the 1980s.

And once you cover the IC designers and applications people in their own lists, what about the thousands of analog geniuses that worked at system companies and could not publish their accomplishments since it would let others copy them? Who where the folks at LeCroy that made their scopes so good? Where are the lists for person at Teledyne that designed one of the cleverest voltage-fed half-bridge converters I have ever seen? And that brings up another important dichotomy: the difference between analog power and analog signal path. Those are two different skill sets. Filters and converters and op-amps are also signal chain subsystems that deserve a list of their own as well as references and temp sensors.

On top of all this we have some of the great signal integrity consultants, Henry Ott, Howard Johnson and Eric Bogatin to name a few. Don’t they deserve a list of their own?

No, there is no such thing as a top ten analog. That is trying to put digital thinking on a real-world analog issue. But feel free to let us know who you think are the analog engineering greats in the comments below.

[Update– Darren Holdstock noted that the IEEE link in his comment below was causing the blog to suppress comments following his, including the great Walt Jung, so I here is the link Darren wanted us to see.]

Some of the cleverist work in analog has been done in nuclear science instrumentation. And, one of the wizards of low noise front ends, in paricular,is Veljko Radeka of Brookhaven National Labs.

Neil Albaugh commented:

First let me thank Walter Jung for his kind remarks-- he is a highly respected analog engineer himself who deserves to be on this list. Walt has written extensively and his books are found on the shelf of most analog engineers. Who hasn't refered to one of his "Cookbooks" to find a useful circuit? Mark Stitt of Burr- Brown was a rare type of engineer. He was extremely creative and I was priviledged to work with him until his untimely death.

Grog commented:

I always though Mark Stitt at Burr Brown was pretty impressive and he had over 50 patents. I know another guy you never heard of with 50 patents, but all of you would know the company where he was head of engineering. It''s really hard to narrow it down to 10 when most engineers haven''t been around long enough to know the history of modern electronics.

Paul Rako commented:

Well, I did not want to date Jim Williams saying HE noticed it 40 years ago-- we are both on our 39th birthday. I also love Ron Mancini, heck he used to wrote for us, how could I forget? I remember when he worked at Harris. He stood in a conference and put a Harris datasheet on the screen. He said, "The first page is all lies." We all looked shocked and a bit uncomfortable. He then said, "Well, perhaps I should clarify. The first page is written by Marketing and the rest is written by Engineering." We all said "Oh, the first page is all lies." He then went on to show how to interpret the histograms and other charts and data in the datasheet so you didn't get burned. A great guy. Many other greats mentioned in the comments as well, and I should have said something about the Gilbert Cell and oscillators when I talked about Barrie. I'll fix Rod's name. If Widlar, an IC designer, goes on top then I would put Pease the apps guy second. Bob is old enough to have designed with discrete components so he is a systems guy at heart, but he also did IC design and we all know he is a great writer and troubleshooter. There is simply no one else like him and I doubt there every will be another analog polymath like him.

Bob Pease commented:

Did Jim Williams really say he noticed HP using 2N4119s as low-leakage diodes, 20 years ago? We were using them 40 years ago at Philbrick. Not a big deal. By the way, the first JFET I ever saw was germanium. I did NOT measure its Ig. Was George Philbrick really a businessman? I''d say he was a dreamer. Many of his computers and amplifiers and concepts were quite DREAMY. So was a lot of his BUSINESS. If Bob Malter hadn''t invented and produced the P2, George A. Philbrick Researches Inc. would probably be still a tiny company. Ask me about George''s 10 MHz square waves. The guy who invented the implanted BiFets was Rod Russell, not Ron. Some guy J. Johnson asked, how do you make a 50-ohm load resistor that can handle 600 kW and is flat to 30 MHz? I''d buy about $100 of Allen Bradley 51-ohm 2-watt resistors, and series-parallel them like mad. Connect them in a low-impedance pattern. Sink ''em into a bucket of oil. No rocket science needed. I''m going to PRESUME that this 600 kW rating was a pulse, NOT dc.... *** I went over this problem a month ago with some customer. He then asked, "How do you measure the flatness of the impedance?" That was tough, but it was OK... Some guy "Brad Wood" suggests that I said, there is no work left for non-IC analog designers to do? At least one of us must have been drunk

J Johnston commented:

Only Top 10? I would add Dave Welland of Crystal Semiconductor. He designed the first true 16 bit SAR ADC (1985) whose specs still outdo most 16 bit SARs today, and the first commercial 4th order delta sigma modulator for audio. These parts revolutionized the industry showing that great analog could be done in standard CMOS. I would remove Bob Pease from the list because Bob thought delta sigma was a flash in the pan back then. I would also remove Bernie Gordon; remember he believed you'd never be able to make anything better than a 12 bit converter. And I agree that Gerald Stanley of Crown is tops. In the mid 70s I used his linear circuit simulator software that he wrote in assembler for the Intel 8080 (Altair 8800 box). The software drove an IBM Selectric typewriter to produce gain and phase plots. So Gerald is much more than an analog engineer. He stacked Crown DC300 amps to build a tester for power transistor SOA performance and both RCA and Motorola paid to buy testers as they couldn't believe it could be done. EDN should sponsor a bar night so we could all sit around and tell old engineer stories (although I don't drink myself).

And don't forget Bob Mammano who just announced his retirement from TI. He designed the first PWM chip for switching power supplies and was key to Unitrode becoming big player in Power and then TI when they bought Unitrode. He has been at the forefront of switching power ICs from the very begging. He also has been the driving force behind those great Unitrode (now TI) power seminars that hit the road every 1.5 years.

Thanks for the cross-reference Paul. Great to see that this is generating the discussion I hoped for (a few days of research over the Christmas break not wasted!). Would be good to have your thoughts on the blog comment I posted alongside this at www.analog-europe.com/blogs/212700742 I have had the pleasure of interviewing some of these people, so as I said in my notes on the methodology, hands-up ? there?s some bias! On a serious note, however, I don?t have a background in analog engineering, so was trying to piece together some sort of historical context for this discipline. How can you judge current engineering achievements without some understanding of the past? Oh, and on the ?Top 10? subject ? I called it something like ?Some great analog engineers? and got no response. When I renamed it ?Top 10?, my inbox started hotting up. Glad I didn?t have to resort to option 3 ? ?Jade Goody?s Top 10 analog engineers? (p.s. Beware Googling her - you have been warned!)

Brad Wood commented:

Baxandall absolutely one of the greats. I recently thought I's stumbled on a topology of great utility, only to find PB had stolen the idea from me in 1966. And reaching back, Alan Blumlein---no telling how much more he would have done had he not had a fatal accident at an early age. Another name I'd forgotten on my previous post was Gerald Stanley, a brilliant power amplifier designer for Crown and also a very nice guy.

Darren Holdstock, UK commented:

Despite their protestations, I'd include Pease and Williams in the list for sure, and I'm, sure Paul Rako would too if journalistic ethics didn't preclude him from nominating friends and ex-colleagues. We're all standing on the shoulders of giants, and I've relied heavily on the work of these two guys over the years. Widlar is a fine choice for #1, no arguments there, plus anyone who buys a sheep as a company lawnmower is alright by me. I also successfully, and satisfyingly, regularly use the technique of Widlarization, which is to hit a faulty component with a big hammer so it doesn't wind up back in the good parts box. While the electronic elite really are the analogue IC designers, particularly those working in the reputable US semi houses, I'd like to plug some home-grown talent: Peter Baxandall - if you've ever used an audio tone control or an LCD screen you'll be using variants of his circuits, and John Linsley Hood for his respected audio designs that refuse to become dated.

Brad Wood commented:

Paul, your point about IC designers getting the publicity is very well-taken. I remember when Pease even showed how limited his POV could be when he suggested in so many words that there was nothing left for non-IC analog designers to do anymore. I laughed about that almost as much as I do when someone tells me I probably don't work anymore in analog design because after all everything is digital now! In those cases I sometimes tell them that every time I hear that argument for my obsolescence, I know that I'll have plenty of work for the forseeable future. Among people not widely recognized that come to mind: Bruce Hofer, one of the co-founders of Audio Precision; John Addis and others at Tektronix, who invented and developed an amazing variety of fast d.c.-to HF amplifiers, and probably understood transistors about as well as anyone---and this in the years when simulators were rare or nonexistent. Reaching back to pre-transistor days: Loebe Julie, who got remarkable performance out of hollow state devices. And there are doubtless many more.

I think reader comments from Mike and Tony reinforce your closing statement...that there is no top ten list. Every reader can add a name or two... my vote: Ray Dolby... raised in San Francisco, he received a B.S. in electrical engineering from Stanford University and subsequently won a Marshall Scholarship for a Ph.D. (1961) in physics from Cambridge University, where he was a Research Fellow at Pembroke College... Dolby Noise Reduction... I'll bet more people worldwide will recognize his name than all those listed above combined. But I agree... you can't make a list...

Mike Demler commented:

Great stuff! I think it's interesting that you never heard of Bernie Gordon. Apparently you never worked in data conversion, as he was (in)famous back in Massachusetts where it all got started (Analogic, Teledyne-Philbrick, Datel, MicroNetworks, Analog Devices...). A couple names you left out: Paul Brokaw should be a no-brainer. The very first analog design book I ever read, that got me hooked, was by Alan Grebene. I actually found it in the public library while I was a college student back in Buffalo, NY and borrowed it over & over & over again, If anyone can find a copy of that for me (the early 70s version), I will buy it off of you!.
