Hi folks,
 
This article:
www.electronicdesign.com/energy/filter-trims-ultra-precision-voltage-reference
is intriguing, but the links to the figures do not work. Could not find in the wayback machine, either (probably pilot error).

Has anyone archived the schematic??

Thanks,
Randall

I am not absolutely sure it is the picture from the article, but I think I have local copy.

However the use of low pass filtering is limited to a voltage reference, as the interesting part is the very low frequency part, like below 0.01 Hz and this is hard to filter.

This particular circuit was already discussed here, if its of interest to you:
