Isn't that resistor a feedback loop?

I played with that setup in the lab many years ago.  It didn't work as well 
as I was expecting.  I didn't figure out why it didn't work better.

Maybe some gain in the feedback path would help.  Then we have to consider 
stability.  Ugh.

These are my opinions, not necessarily my employer's.  I hate spam.
