If it's any consolation: the physical origin of certain types of noise 
in semiconductors is still a hotly debated topic. Unless you're being 
tasked with reducing the noise for a semiconductor device, you can 
safely skip the part about the origin and just deal with the result.

You're welcome. Let me know how you've managed to squeeze that much 
googling into less than a day, I should have a few good uses for that 
trick... :-)
