Yes, Scott, some people need something to wipe their butt with.
(Some people might think 132 is the appropriate place)

Of course, with Maxwell, you have to remove the symmetry, for Maxwell said it is asymmetrical. Thus - unidirectional. And elastic. Also... toss back in all the complex minor components that Heaviside threw away. Then you'll actually have the proper functional equations.We've been blocked from really figuring things out due to Maxwell's works being bastardized into a circular argument/proposition.....that they never were.
You have to back to the original full equations.
My point was one of how we may have people who developed such things in an act of thinking that was in the quantum realm or context, but the analysis in application should remain in the same arena. This, once the basic Newtonian equations of complex LCR are done with. More in the direction that the signal is not a set of numbers, as many will interpret - that it is something that never steps out of the quantum arena, and it interacts like a plasma or ionic consideration.

Scott,
We are talking about specialized markets that can afford the cost.
As to getting costs in line I assume you are familiar with Mosis?

Do you know the history behind it?
You don't find any proprietary high voltage linear processes on this list and you won't. The best avenue here is for the OEM to go directly to the custom fab house and get exactly what they want.
You also will never find a good P-JFET on any of their processes.
not quite. scientific methodology has it's roots deeply tied into the idea of of the philosophic argument.
Intelligence is plastic.
Addition to the singular leg of linear thinking (the core issue in the current downward spiral of psychology expressed as/through science) can bring new or lost capacities back to the table, in order to a further an argument in physics that has quite clearly gone circular and limited in it's path.
High end audio is a multi-pronged, multifaceted endeavor. Thus it encompasses more than the basics, and tends to reach the edge of our given individual varied capacities. Thus the given person who is attempting cognate, must, like the physician, heal the given self.
John is no so fond of it when I put such things (as this post ) in this thread, for various reasons, none of which are, from the conversations.... selfish.
It is rather more of a periodic reminder that the thing one cannot find is either not in a recognized shape or it is not in the field that is being interviewed.
And that like an athlete attempting to be the best in the world, one has to stretch one's abilities, in the personal sense. In this case, it is the given current limits of the mind, which we all have in one way or another. That the limits of physical endeavor end up encompassing many issues and components of the given athlete's life.
If one is experimenting, and attempting to discern and find limits... and surpass them, the the problem is also one of the self, and not specifically or solely within the field in question, as psychological directives and origins go. That using the one leg of externalized linearity in thinking will find one hobbled before they even begin.
Ie, non-blinkered and open minded realization --begets intelligence.

Did you look at the "Trusted Foundry" processes available only to DoD approved customers?
I assume you are aware of the "Trusted Foundry" issues.
A bunch of IBM mostly CMOS processes. IBM has no interest in +-15V op-amps.
We did once as a favor to MIT make complimentary pairs of NPN's and PNP's to replace the RHOM transistors. They didn't work in their circuit due to quasi-sat issues. I never found evidence of them going forward with patenting the circuit they were working on.
I had the same problem with my patented JC-1 design, decades ago with the ultra low noise Hitachi complementary bipolars. They would NOT work properly. Rohm or Fairchild 2A devices worked OK, however. So this is quasi-stat? Do you see a problem on the curve tracer? I did, with my problem.
sorry couldn't resistActually the IBM "Trusted" foundry does have a single customer who needs some analog processes! Very small quantities of very high quality devices and a large budget.
John, have you had any experience with the low rbb' Toshibas (2SA1316, 2SC3329)? They are also gone now. One guy I recommended them to apparently thought they would have especially low current noise (no, although the high beta sorts manage some decent numbers), but otherwise thought they were o.k.
Quasi-sat makes them very non-linear at low Vce. I think you will find a corellation between most very low noise transistors and very low Vsat, I think some are only 25mV or less. You can see this on a classic curve tracer if you know what to look for.
A quick look and the 2N4401 looks ordinary but our SSM duals are 26mV typ., but the 2N4401 is not specifically ultra low noise. THAT lists 50mV on both flavors of theirs.
