[sdiy] Low voltage noise source

[karl dalen]

Im trying to do a low voltage noise generator,im talking about
a all analog (no shift register)at +5V supply with at least
1V P to P output!

This has shown to be difficult, its quite hard to get a PN
junktion to "noise" (grounded diode coupling, zener or the 
typical NPN back to back coupling) at these voltages,
if it does there is too much DC after up gaining stages
that popping ocurrs even with DC blockler. Or the final
noise are very collored due to the gain structure, allmost
band passed! Also due to massove gain its quite sensitive
to hum from varius sources!

Any ideas folks on low voltage wite noise generators!

Thanks!
