It strikes me that over the years there have been some threads on this forum that have been really good. But after they have run their course they can be difficult to find. If you can recall, find, and post the url to threads that you have though have been very helpful and of wide interest, I will try to find a way to highlight these threads so that more people can benefit from them.

Thanks in advance!

The threads with the highest read counts might be good candidates.

This is good:
"65298","The History of SPICE","https://designers-guide.org/forum/YaBB.pl?num=1375700540"

You (Ken) make a good point about the merits of stb vs a low-pass filter here:
"48781","AC analysis","https://designers-guide.org/forum/YaBB.pl?num=1155668476"

And transcapacitances are commonly misunderstood:
"23177","Cgs, Cgg, CGd etc. in cadence","https://designers-guide.org/forum/YaBB.pl?num=1087411058"

Here:
"53925","Using a SPICE subcircuit in Spectre","https://designers-guide.org/forum/YaBB.pl?num=1191334088"

it seems like it would be more helpful to present a summary of the "best" way to do this and the common mistakes, rather than just "pinning" the topic. It's a little hard to skim through it and get the key details.
