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.
