I am trying to measure a base spreading resistance(Rbb').
I have some power supplies and multimeters.
If someone have an idea to measure Rbb' by just using several power supplies and multimeters, let me know.
 

Hello,

Do a search on: gummel poon bipolar model model description parameter extraction. This may guide you to an agilent document describing how to extract Rbb'.

If can't find the document, please contact me again.
 

Hi WimRFP,

Thank you for your reply.
I found it.
I will try.
Thanks a lot!
