My chip design customers are almost always on the leading edge of
their particular technology.
As such, publishing the design I did for them would divulge their
proprietary information to competitors; and, of course, I am bound by
NDA's to keep that information confidential.
But here is an eleven year old design that can now be freely
published... typical of my designs in an advanced BiCMOS technology...

As you can see, I don't deal in the simple stuff :-}

Just a schematic isn't really a complete description of an IC design,
especially when we don't have the process book and can't look up the
device characteristics.
Sheeesh! Do you need a process book to know what an NPN or an MOS
device does ?
How about some discussion of what it is, what it does, and how? Start
with the high points.
I thought all that was required here on S.E.D was posting a schematic
without any defense, just claiming how wonderful it is ?:-}
However, the posted schematic is a multi-channel SONAR system. Quite
sophisticated, with tunable filters, voltage-variable amplifiers and
all kinds of temperature compensation.
I'll write something up. It'll be awhile, getting quite busy again.
I'll post the temperature compensation stuff first... easy for me...
and it'll keep the plebes occupied for months.
Gosh, Mr. Thompson, you're so wonderful--can I have your autograph,
pretty please?
Cheers
Phil Hobbs
What? You want a signed photograph ?:-}
