In the data sheet for one of the op-amps I use it says that it has "ultra-low input bias current: 2fA" What does the f stand for? Presumably it's the next step along from pico, but what IS the next step along from pico?
I know it doesn't really matter - it's low and that's all I need to know - I was just curious (couldn't find anything when I googled it).
That's a "femtoampere", which is 10^-15, one quadrillionth of an ampere. That's GOT to be a CMOS opamp!.

Sounds like a sanitary product! Thanks for the reply Brett, yes it is CMOS (what else!) :D
