It's also true for many, many things, probably including laundry detergent. Certainly true for houses, and the stock market. Attached is brief review of a good book on the subject.

... and now back to our (ir)regular program:
Witness the absolute cheapest way to do loop gain measurements:

If you have a student ID the AD module is just $99 in the US.

The lab kit is packed with parts too. Doug is retired like me and this is his show.
Me three, although I'm still a "student" mostly (postdocs sit in this neither here nor there world) so pretty sure I qualify for the educational discount.
^ I'm maintaining a decent work:life balance for now, but well, I took the postdoc over going into industry not because I see myself staying in academia for a long time, but the opportunity here to be on the leading edge of translational (read: commercialization) technology is great and the center is new. So it's a great chance to get in on some really good work, which I'm sure the folks who follow this thread can appreciate. As soon as my lab stuff gets into full swing, I'm sure my posting rate will drop precipitously, and your blood pressure can stabilize. 😉 We'll see!
I recently learned a familiar life lesson, yesterday. A colleague PROOFED one of the developmental schematics that I am working on. This prototype has challenged me to behave the way that I would normally expect, and I have spent extra time trying to find out why. My associate, (not someone that I typically work with today) who is independently employed in Silicon Valley as an analog design engineer, found a number of serious omissions or commissions on the schematic that I overlooked or was concerned about, but unsure of why.
Here, the breakthrough was putting an independent eye on the project, someone who only wants to help, and not to make me look foolish, like some might want to. Thanks Sonny, my summer hire in 1981, and now an active engineer himself.

Congratulations on the collaborative success! Would any of the weaknesses (if that's the right word) have appeared in SPICE simulation results? Keeping in mind that SPICE only answers the questions you ask it, not the questions that you later wish you had asked it.
No Mark, not really, in this case. If I DID model the whole amp in SPICE then I might have caught one or two things, but not 5 things or more.
There seems to be adicthotomy here. You guys are lookinh gor etter circuits, while I seem to be searchnig for a personal upgrade. On Monday, my wife paid off thw hispital to let me go gome after having operated on my left hip. One down, one to go, later in in September ot October. The bill was about US$ 100 all told, we still have a fairly socially orientated health plan in this country.
For the technies among you, I have taken the first step towards being cyber man. having had some titaniuam scgrew installed. For one thing, a lot pain is gone, although I have yet to execrsise to really get there. First using twp crutche, then just oe, then a cane and eventuall nor needig any of them.
But Lordy, it's good to be back.

Gents, can I ask for your view on a technical issue. I am in a discussion off-forum on the pros and cons of wide open loop bandwidth.
I know, I know, but please hear me out. My question is about a specific reason that was given to me why wide open loop bandwidth was a Good Thing.
The reasoning is that to have a small OL BW, like some opamp that rolls off OL from 10Hz, requires a larger dominant compensation cap, than one that starts to roll off at say 10kHz, that only needs a small dominant comp cap.
Then I was given a few reasons why a smaller cap would be better, but I'll save that for next.
So: is it true, as a principle, that low frequency roll off requires a larger dominant comp cap than a high frequency roll off?
