A collection of monographs on high accuracy electronics

===============================================

If as stated "the thermal noise power dissipated in an unloaded resistor" is nonzero, a reel of 0805s is a fire hazard. What would noise power mean if it can't be extracted or dissipated or even measured?

I'm now designing a signal generator that would be more sellable if it had lower voltage noise density. Given that I've got the noise as low as I can without cryogenics, around 8 nV/rtHz, the only thing left is to average multiple channels. Noise declines as the square root of applied dollars.

If there are enough people willing to read Chris’s doc carefully, maybe we could put together an errata list so that John M. could issue a corrected version.

That would probably make it more useful, and so a better memorial.

No taxation without representation No chilli without beans No fluctuation without dissipation

Which one is true?

No motion without perpetual, apparently. ;)

No trolls without Australia. Actually, I thought your idea of correcting the document had much merit, Phil. You and the other big shots here can get down to the task. I'll make the tea and correct the spelling. :-)

If anybody's interested, sure.

Of course John M has obviously never been to Texas, if he thinks that all chili has beans. ;)

You're lucky it's not one of my drafts, in which case there would be typos on every line!

You're not seeing the wood for the trees.

Daykin's industrial experience was gained at ASL whose primary products were thermometry bridges. They had a resolution of about a mK. To achieve this the resistance thermometers are part of an ac bridge (the other leg being a ratio transformer) followed by a synchronous detector.

These monographs all basically discuss the electronics used in these bridges.

An AC bridge. That wasn't mentioned in that section, but yes, that would work. That's another suggestion for improving the text then.
