ANN: Updated Models & Schematics on My Website

I have updated my Device Models & Subcircuits page. Comments invited. I welcome suggestions of models you'd like to see created.

With years of benign neglect, I've accumulated more than 600 schematics on my S.E.D/Schematics page. So I'm busy indexing everything... after two days of work I'm just up to "H" :-(

I'm also coalescing topics, so that sequential improvements, as discussions of a problem evolved, will be combined and a descriptive cover added where appropriate. Again, comments welcome.

Where possible, graphics from the OP's problem statement will be added.

The names of OP's proven to be assholes will be rendered anonymous... that is their names will be replaced with "some asshole" >:-}

August 31...

New updates to my Device Models & Subcircuits page.

New updates to my Simulation Tools & Macros page.

With years of benign neglect, I've accumulated more than 600 schematics on my S.E.D/Schematics page. So I'm busy indexing everything...

after more work I'm now up to "O" >:-]

Comments welcome. Also suggestions about what to add. ...Jim Thompson

Why not write a book and actually help the next generation (or the one after that)?

Perhaps introduce Jim to your publisher?

I'm only impolite with idiots. Ask around. Engineers under 40 thinks I walk on water. Those over 40 fear I'm after their job... I'm not, I'm only interested in "fun with circuits" >:-] ...Jim Thompson

The old guy, George Telecki, retired about a year ago. He was great--I'd been working with him since about 1998. I don't know the new person yet.

I have a couple of projects underway, one for a third edition of BEOS, and a small monograph on photon budgets that I may send to SPIE or someplace like that if I ever get it done.

Most of Jim's NDAs must have expired by now, so he could write about probably 90% of the things he's done if he wanted to.

Cheers

Yes. I'd like to talk. It's offensive to me to endure certain assholes who are fond of implying I haven't done anything. (But I still need to get many releases... much of what I've done is current technology... I still have patent applications in progress.)

I may be physically old, but I'm certainly not mentally. ...Jim Thompson

Permission to publish isn't generally too hard to get, I wouldn't think. Better get started if you're ever going to, though--if your experience is like mine, it'll take you a solid year of writing and calculating, even if you do it really truly full time.

(At IBM in the late 90s, I was blessed with very understanding managers. When I went into my annual performance review for 1998, I somewhat nervously told them that no, I really hadn't done any of what we'd agreed to for that year, but then plunked down a binder containing my nearly completed book manuscript. Not only did I survive, but they gave me a nice raise.)

Fortunately I now keep copious notes about my designs... provoked by the Chrysler ignition controller fiasco... I looked back at a 40 year old design and couldn't figure out how/why it worked... took me over a week to reconstruct how/why I designed it that way >:-] ...Jim Thompson

That's good, but for the book to be useful it should IMO be a bit more than just a Cooks' tour of Jim's designs, laid out for the admiring multitude. ;) That takes a fair amount of work.

Generalizing the design approaches to make the book more of an apprenticeship-in-a-box does the most good, I think. There are lots of books that talk about _what_ people have done, but not so many that talk about _why_, and very few indeed that give much of a clue about which ones to chose for a given problem.

Actually, I wrote (and presented) a series of seminars for ICE that cover the nuts and bolts of bipolar design. I could modernize something like that. ...Jim Thompson

FWIW, I like reading about battles obtaining solutions that relate to what I'm doing. I also like theory and generalization, but since form my 'own' ideas while reading about the battles I usually discount generalized solutions as that, generalized and 'not fitting my needs' In other words, when writing; you must address the potential of diluting your information down into bland generalizations versus leaving the sharp, cusps of the solutions intact. Not a task I envy you for. However, you might be able to walk a fine line between the two by relating the 'parameters', the 'gotcha's, that determine an optimized solution. In other words, while relating detailed solutions to specific problems keep in focus that vision of possible solutions, telling why not this, why not that, telling the tradeoffs, telling the what-ifs.

Reading such papers is like looking over one's mentor's shoulders and listening to the musings of why this, and why not that.

Do you need a semi-proof reader?

Most of the advanced amplifier books that I know about present things like the f_T doubler as though they sprang from the forehead of Zeus, and then analyze them. Something about all the messing around you have to do in order to come up with a useful new topology would be really useful.

Hollister, which is the best of the bunch, has a sort of iterative progression that I like a lot, but there's something about discovering a new-to-you topology that makes it your own somehow. Increases the confidence level, anyway. I reinvented some of the classical small circuits before I knew that they were classical--I expect that many of us who started out as hobbyists did.

I probably do better with students around me asking questions than I do just writing an explanation.

"Musings" _are_ much better than bland analysis.

Other problem I have is that I'm self-taught in CMOS... designing by winging it ;-) Sometimes presents problems...

Invariably, when I'm trying to nail down a contract, some PhD comes along and springs a "school-book" CMOS equation question on me... which I can't answer. Then, the PhD tries coming in for the kill and throws a schematic in front of me... only problem is I quickly pointed out the flaws in the design. PhD didn't like that. Happened to me just a few weeks ago at a major semiconductor house (in Tempe, you guess which one ;-) I didn't get the contract. ...Jim Thompson

Greetings Phil, What you said about discovering something new to you makes a lot of sense. Partly because you then understand it. When trying to understand the Heisenberg Uncertainty Principle I thought about it but didn't really get it. But when I thought of a mechanism that illustrated to me how it worked it all clicked. Sometime later I read an article that used the same explanation that I had "invented". I was not surprised of course. Good ideas, because they are good ideas, tend to be discovered by lots of folks.
