1/f noise in transistors

[seanvn]

As far as I understand there has never been a satisfactory explanation of 1/f noise in transistors. Given that transistors must be the most studied form of physical device in existence both theoretically and practically that seems a little odd. I have just been reading about the GEO600 experiment in Germany that aims to detect gravity waves. Well they didn't find any but what they did find was an unexpected source of noise in there system that they could not account for. It has been put forward as a suggestion that this noise is actually 'holographic noise' that is present in the space-time structure of the universe. If true then it would be reminiscent of the discovery of the cosmic background radiation by Pinziaz and Wilson in 1964.
Perhaps we have beaten the GEO600 team to it and our humble little transistors are detecting the 'holographic noise' of the universe as 1/f noise?

Hi seanvn
The attached article from 1993 provides insight into I/f noise in semiconductors. Simply put as I read the correct use of current in a circuit can dramatically benefit the unwanted ingress of noise, and as current reduces -so does bandwidth.

I reflect on the lifetime work of David Blackmer founder of DBX and his quest for higher bandwidth in audio David E. Blackmer - Wikipedia, the free encyclopedia

Ben Duncan audio engineer, to the best of my knowledge has contributed extensively in measuring real components that we use in electronics and discovery of noise and its
side effects. He has also led many an engineer toward Robert Pirsigs book Zen and the Art of Motorcycle Maintenance an important book describing in part the difference of persons who are analytical vs those who gloss over fine detail.
