So I was planning on using those 1/f macro's that Bill Sands did some years back - I know I have seen a succinct description of how to set up the 3 parameters inside, and the header is pretty clear also, but is the good reference I should be using. The file here refers to the original Analogzone article (long gone)
TINA Noise Sources revC (1).TSC
I did find this, which has what I want in the Build your own model section, but kind of an obscure link - hopefully there is a more direct TI reference I could use for this - or equivalent - I tried to find that TINA noise analysis folder but could not? So like figure 4-10 is what I am looking for in a TI document if possible.
