I built this project with a few minor mods;
http://www.edn.com/design/analog/4420926/White-noise-source-flat-from-1Hz-to-100kHz
It generates fairly good noise which is closer to "blue" noise up to 11025 hz.
But I read that by reducing the reverse bias current near the breakdown "knee", instability and extreme sensitivity can be induced in the output signal. That is, perhaps strangely, exactly the effect I want.
So the question is: how do I modify the circuit to put it in this unstable mode?
