I just found out... Tom Frederiksen, RIP...

Tom and I shared a cubicle at Motorola Semiconductor Products Division
during the early to mid-60's.

So what integrated circuits did he design?

I'd never even heard of the guy, so my ignorance is on display. If Jim actually knew the part number of any IC Frederiksen designed, I presume he'd have posted it, so Jim's ignorance is displayed equally clearly.

 I have four from his set of "Intuitive" Circuit Design books,
 and enjoyed them very much.  It's sad to see the good ones go.

Indeed!

Many of my creations (AND Tom's) were due to the fact that we
constantly battered (and/or taunted) each other's designs, resulting
in superb outcomes.

The "Thompson" current mirror in this link...

<http://www.analog-innovations.com/SED/EnhancedCurrentMirrors.pdf>

came about from a "coffee-bet" with Tom that I couldn't possibly make
a lateral-PNP current mirror with a stable output.

Likewise...

<http://www.analog-innovations.com/SED/MC1554-DataSheet.pdf>

was a joint effort.

And many others.

(I'm referenced on page 14-15 of Tom's "Intuitive IC Op Amps")

You might just have an ego problem when the occasion of a man's death is 
used promote yourself.  Your ego has no bounds, does it?

THAT'S how you read that? Jim was talking about working with Tom. 
Sounds like mutual respect to me.

But Jim can't name an integrated circuit he designed. He can remember that the guy prompted Jim to come up with an interesting innovation, but can't bring himself to document anything Frederiksen himself was responsible for.

Trump and Larkin behave like that.

 I know he was a specialist in high-power IC design,
 see his 1968 paper in JSSC, "A Monolithic High-Power
 Series Voltage Regulator", and with James Solomon,
 "A High-Performance 3-Watt Monolithic Class-B Power
 Amplifier"; both were probably Motorola parts.  And
 I have his paper on a Monolithic-Sonar-System.  There
 are likely many more papers if one were to look.  He
 also had patents, which I have stored in my computer.

You know you're old when you realize you have worked with most of
those co-inventors ;-)

 Well, we see from the patents he seemed to have quickly
 moved to NSC.  You were there, please tell us more of
 Tom's story.  And about these papers and patents, which
 product part numbers do they correspond to?

Most of the co-inventors were young bucks at Motorola when I was
there, who then fled to NSC with Solomon and Frederiksen.  That's how
I recognize the names.

I'll browse the patents and can probably identify those products that
are Motorola's.

As for those at NSC, I might, or might not, be able to guess products.

I was never at NSC... my foray into Californica was to Philco-Ford for
8 months in 1968 along with John Welty, then right back to Motorola.

 I'm curious about the two Motorola papers I quoted.

 Yes, the NSC scene, as in the patents, needs to be filled
 out by somebody else, and sadly it can't be Bob Pease!

I'm not sure they are Motorola papers.  By 1968, they both may have
left Motorola... there was some turmoil in those days ;-)

 Both papers list Motorola affiliation, that is they were
 Motorola paid-for projects.  Check them out on DropBox.

The first paper looks as if it might correspond to the LM4871 - which is not a number I ever ran into, and sounds a good deal later than 1968. The LM380 and 
LM384 seem to fit the bill better - the LM380 is credited with  2.5W on the data sheet, and the LM3284 was a selected part that could survive a higher supply voltage and was rated for 5W.

http://www.ti.com/lit/ds/symlink/lm380.pdf

The second part is a voltage regulator, and Bob Widlar managed to corner most of the glory there.
