Paul Rako

Paul RakoHi, I'm Paul Rako. I not only write about analog, I love analog. Heck, I am analog. I consider analog to be the highest calling one can have in this world.

Like a lot of analog engineers I got into analog because of my interest in music. I was hacking up JFET amplifiers for my Stratocaster and playing with those old bucket-brigade ICs from Radio Shack back in the early 1980s. Back then all my pals told me to go digital. It felt like an opium den, all the constant social pressure to "go digital." They told me the future was digital and if I didn't "go digital" I would be homeless and begging on the streets of Silicon Valley with a tin cup.

Well, the joke is on them. I followed my passion and read every EDN magazine cover-to-cover. (That is why I am so honored and feel such a responsibility to carry on the torch here.) Today we all know that analog engineers command a significant salary advantage and all the outsourced jobs were software and digital. I get calls from headhunters every day and my old boss Al Kelsch told me that an analog IC designer is never without a job.

I am proud because I chose analog before analog was cool and back when we all thought it would be a personal and professional sacrifice to be analog. How nicely it has worked out that society has recognized the intrinsic value in people that can conceive, analyze, and create in shades of grey rather than just the simplistic black and white of digital or the clerical work of software.

I shudder when Wired magazine uses "analog" as a term of opprobrium, such as saying: "That is so analog, you idiot." They are the idiots. I was at my pal Dave Ruigh's shop. He owns a record lathe. He mentioned that a fresh-cut shellac master has better signal-to-noise than a CD. I scoffed, "Heck Dave, a CD is 16 bits and that is 96 dB right there with no oversampling or dithering or anything else." So he cuts a record from his 24 track 2-inch tape deck. The needle hits the record and there is the thump, but no hiss or clicks or pops. This is a virgin shellac—just playing it ruins it, you are supposed to make a copper master from it to press vinyl. The music starts. Wow, 118 dB. Yeah, I can vouch for it, better than a CD.

Another friend has one of those old 5W analog car phones, the ones with the regular old-style handset and an enclosure the size of a toaster. He doesn't have any dropped calls or out-of-range problems. He gets reception in tunnels and everywhere in downtown Oakland or San Francisco.

So don't skwunch up your nose and tell me that analog is inferior. I will be too busy filing you under "moron" to hear anything you say after that.

I was at an analog conference years ago and a boss said it was easier to teach an analog person digital than to teach a digital person analog. The room exploded in laughter. No kidding, Sherlock. Analog is hard. That's why it attracts such interesting people.

In fact, the people you get to hang around with are the real reason to love analog. Analog has the...how shall I say? Characters. My pal Bob Pease. Wild Bill Klein down in Texas. And analog has women, and the best ones on the planet: Bonnie Baker and EDN's very own Margery Conner, for example. Don't forget Jim Williams and Ron Mancini and all the crazy IC designers like Widlar, Fullagar, Erdi, Jung, and Fredrickson. Every one of them a personality and every one a joy to hang around with. Heck, just call up EDN's former analog editor, Joshua Israelsohn, and ask him what kind of shoes he's wearing.

Now, there is nothing wrong with digital. As an analog guy I like digital and as a consultant I spent plenty of time writing machine code for Z-80s on up to Atmels. An embedded system is even more analog than pure analog since it includes mixed-signal elements.

I like all electronics, but I love analog. I hope you will love analog too.

AWR gives a free year of Microwave Office to every graduating engineer

One of the exciting things that happened yesterday at the Electrical and Computer Engineering Department Heads Association conference in Clearwater Florida is that Sherry Hess, vice president of marketing for AWR announced their Graduate Gift Initiative. To a gasp of the 100 engineering department heads in the room, she explained that AWR would give every EE graduate, undergrad or post-graduate a free copy of AWR’s software tools for microwave and analog design. The tools can also do signal integrity as I explained in my recent article coming out this Thursday. From the press release:

AWR Corporation, the innovation leader in high-frequency EDA, today announced the AWR Graduate Gift Initiative, which will provide qualifie...Read More

MontaVista’s Alexander Kaliadin on the instant shutdown of a Linux OS

I had a great interview with the architects of MontaVista Software's 1-second boot-time real-time Linux. After the interview went to press it occurred to me to ask Alexander Kaliadin a related question. If smart people like him can figure out how to boot a computer in less than a second, is it also possible to turn the computer off in a short time? His answer was that you could possibly just flip the power switch, if the hardware was designed to allow this. His response and elaboration are below.

There is no problem to shutdown the kernel within 250ms or less. However network and file operations might affect this scenario - for example if your stack is waiting for network hands shake to complete with server in another country or you need to dump 8-16-...Read More

Analog film - the attempt to save Polaroid film

Well, I know analog guru Jim Williams was disturbed that he would not be able to get Polaroid film for his oscilloscope camera. Jim is an analog guy, after all, so he does not typically use digital scopes where you can take a screen shot. He does have a big stash of film in his freezer. Now there may be hope for the industrial and medical Polaroid films, there are companies that will keep supplying them,. But consumers and professional photographers have been left out in the cold. So I was delighted to see that a comp any is trying to keep Polaroid film in production. From the press release I received a few days ago:.

The Impossible Project saved the last Polaroid film production plant in The Netherlands in 2008 and was since then re-inventing a new Instant Film for Polaroid Cameras.

$400 1.3GHz vector network analyzer, and a couple of tiny oscilloscopes

My buddy Phil Stittner came to the last analog breakfast with a network analyzer he made from a kit. The kit is based on this nice article by Prof. Dr. Thomas C. Baier, DG8SAQ (pdf), the designer of the circuit. The only problem Phil had was that the oscillator in the analyzer needed very specific transistors in order to work.  Phil tried substituting some he had handy and it would not oscillate. Since there is an RF signal path in this kit they warn people they need to be experienced, which to me means any production tech could whip one out, but if you are a PhD, you better buy the thing pre-assembled. “Doctor, put the soldering iron down and step away from the bench!”

ADC noise article and all about delta-sigma converters

Dave Van Ess, an apps engineer over at Cypress Semiconductor has a nice article about ADC noise over at Electronic Design. Now me, being an analog curmudgeon, I don’t see how you can call “noise” something deterministic like ADC quantization error, but that it what everybody seems to be calling it. Maybe it is like when the digital guys started calling bus-width bandwidth, because lets face it, bandwidth is a pretty cool word. Anyway, Dave brings up an important concept and a critical factor for preparing your signal path error budgets. EDN’s Bonnie Baker wrote about noise here, and ...Read More
