measuring hfe / beta

gain · 14th May 2008, 09:58 AM

hi all. just wondering if this circuit is OK for measuring hfe in transistors for beta-matching purposes. it seems to agree with what i know about electronics theory, just wanted to post it here to make sure there wasn't something i was missing or perhaps an easier way.

thank you.
