as we know, flicker noise spectral density is 1/f and its power is ln(f); but when we integrate from a lower end to a higher end, if the lower end tends to approach zero frequency, the total power integrated tends to approach infinity. in razavi's book, it is explained as that this phenomenon is a long term effect due to the extremely low frequency, like aging. so my question is, in real design or calculation, what is the lower end of the frequency to choose?
thanks in advance!
