VunderBar, I have never seen a better lecture on NOISE.
But Then, I came from a military that liked to give
self study courses with no instructors.
They called it BEEP school.
They only teach you enough to be Dangerous, not successful.

I wish I had instructors earlier in my younger life like the fellow
teaching that subject matter on you tube.

What is the noise at DC ?? it seems a voltage regulator might do better.

I have heard below 1Hz you want to use bipolar devices only ??

What about cosmic rays and ...

I hear that diodes can be used for a geiger counter and
op amps are full of diodes.

There has to be one best opamp for 100Hz to 100seconds,
What Op Amp is it ??

One best opamp in the whole universe.

It would be so much easier if you could just
ask an egghead some where to tell you the truth
as to which is the one and only low noise op amp to use
below 1Hz. I bet it would be cooled with liquid hydrogen.
Who can afford that ?

regards,
geoff
