Low frequency Stability - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

i'm new too all this...hope to learn from this forum.
what's the best way to obtain stability for HBT for 50 MHz to 1 GHz band for values for IC design. I tried feedback but the Cfb in the feedback loop is having too much affect on the bandwith and requires a big values for IC design (close to 40 pF). Shouldn't Cfb actually just provide blocking without much affecting the ac response? thanks a lot!!
