Hi all
Could you please tell me what is the key factor of amp's flicker noise (1/f noise)
I was testing noise performance of OPA335, and I found the flicker noise (1/f noise) is very small. Could you please explain why the 1/f noise of OPA335 is much lower than others.
I know it's an auto-zero amp, so its high frequency noise would fold back to low frequency, is 1/f noise also related to auto-zero topology?
