CCS-loaded P-fet with bootstrapped drain load on the input FET.

Will there be feedback around that? The gain as-is isn\'t well defined I
don\'t think

Some people invent stuff which is novel enough to patent. John Larkin doesn\'t seem to be one of them.

I\'m looking forward to him inventing my current mirror variation on Baxandall\'s class-D oscillator (which nobody has bothered to patent, but I\'ve not seen anywhere either).

It\'s a big dumb booster. It\'s cheap, it\'s slow, its current gain is very
large.

Nothing wrong with that. Nothing intrinsically \"wrong\" with a Big Mac
aside from possible moral quandaries over the sustainability and methods
of the factory farm meat industry that vegetarians, non-Americans, and
Hitler would contemplate. Sometimes a Big Mac is just what the...ok well

The only boss I ever had was just the opposite. I won an argument
with him over a technical design point. He was a Ph.D. in
biomedical electronics. I was 19 and had taught myself
electronics over the past 1.5 years. When the internet came to my
region 28 years later, I found his email address and contacted
him. One of the first things he said in his reply was to mention
that project and went on to say \"You taught me a good lesson that
day......\"

The general term for that was, in my experience,\'insubordination\'.

Not always. I managed to get around the mechanical boffin once,
getting my department head to forward rough sketches to a vendor,
for what mech had assured us was a dead end. The (cheap!)quote
and free, fully-functioning samples came back in less than 5
business days.
.. . . . and then the mech guy got his hands on the sketches, to
enter them into the CAD system. Although the results did actually
function (well, mostly - with a lerger temperature rise, oversized
profile and 30% more dollar-per-inch 3xfep litz),the additional
details, ovesized dimensioning (for tolerance) and general
messing about made the part an embarrassment to introduce into
production.

Read The X-Chapters. It has some interesting circuits.

I\'ve known people who think that all circuits come from books. They
don\'t explain how those circuits got into books.

This is an electronic design discussion group. I figure that a couple
of per cent of the people who post here can actually design (or even

There are a lot of good circuits in books, and - if the book is well written and properly indexed - you can usually find something useful a lot faster than you can invent it. Most people do understand that somebody invented every last one of the circuits that get into books - and that most them are now obvious to those skilled in the art.

This is an electronic design discussion group. I figure that a couple
of per cent of the people who post here can actually design (or even
understand) circuits,

I would like to know how John Larkin thinks he figured that out. He\'s much more interested in presenting his own circuits than he is in commenting on other people\'s. Presumably he figures that people who don\'t admire his circuits can\'t understand them, and neglects the cases where they are perfectly comprehensible but less than admirable.

> which is why the rest are so active in off-topic blather, where their rightness or wrongness is un-provable and their responses to ideas are mostly childish insults.

John Larkin\'s off-topic opinions about climate change do happen to be wrong, and this is demonstrable, but not in any way that he can recognise, and he does get testy when people point this out.

his email address and contacted him. One of the first things he said in
his reply was to mention that project and went on to say \"You taught me
a good lesson that day......\"

I\'ve been very fortunate in managers. My first one was a fine microwave
engineer named Josef Fikart, who escaped from Czechoslovakia in 1968 and
proceeded to mentor three generations of young radio engineers including
yours truly.

When I left there and went to grad school, I didn\'t always get on with
my thesis adviser Gordon Kino, but he taught me a great deal and always
fought my corner, something that does not grow on trees.

At IBM I had one boss who was too chicken to take even smart risks--a
nice enough old buffer but frustrating to work for. I shopped my
project around to other departments and eventually wound up in Packaging
Research, which was a strange place to be doing antenna-coupled MIM
tunnel junctions, but hey, they were nice guys who signed my purchase
reqs.

I\'ve only ever had one really bad one, also at IBM but a decade earlier.
He was the guy who I worked for as a postdoc when I was 28 years old.
My postdoc project was weird--it was to take the interferometric-readout
attractive-mode atomic force microscope and make a product out of it.
It was called the SXM, for \"scanned anything microscope\", and wound up
being sold by IBM for some years and then by Veeco for another 20 years
or so.

The root of the trouble was that my expertise overlapped my boss\'s,
specifically in the area of measurement physics and optics. He really
wanted to micromanage the project, even though I had two years\' product
design experience and was a circuits guy from way back. He was a very
theoretically-oriented EE with zero product experience. His optics was
okay, but his circuit ideas were, speaking charitably, naive.

He was also a political operator and rather vain, so to get his way, he
set up a group meeting and presented his ideas on how my gizmo should
work. This left me with two choices of how to fail. First, I could
knuckle under and build something that I knew wouldn\'t work, or second,
I could take his proposal apart in public and not have my post-doc
renewed. (I had a wife and daughter at this point.)

I naturally chose #2.

The following week, he did it again, and I did it again. That was when
he stopped coming round to my lab at the end of the day to see how
things were going, so I realized I needed to switch groups fast. Once
the SXM was transferred to the product group in Boca Raton, I jumped
over to another group run by a very smart guy named Sam Batchelder,
who\'s been a friend from that day to this. He got my postdoc renewed
and found the right project for me to work on to get me hired as a
research staff member. (Sam is really one of the ones.)

I think it was mighty gracious of my former boss to acknowledge
that he could learn something from a self-taught teenager. He was
a New Zealander working in the US and was on loan to the
institution. It was he who invited me to work at the medical
institution when I was a patient there, some 3000 km from home.
We had some good times together.

We built a prototype for a new type of artificial pacemaker. I
helped design a digital patient monitoring system. He mentioned
those things too when we briefly renewed contact after nearly 30
years. I did some work of my own for the labs and for the
Wellcome Research wing which was headed by Dr.James Baker, an
American. I was in the midst of designing a heart-lung machine
when I left.

At the same time, I was also responsible for the maintenance of
practically all the electrical and electronic equipment in the
institution which was then one of the biggest in Asia. When I
complained that my workload was a bit too much for one person, my
boss said that it was too much for five people.
