Hi,
I was reading an application note from ADI (AN-968) about current sources and saw a circuit below.
The note only had basic description of the circuit and I'm wondering how the circuit works (especially D1, D2, Q1 and Q2)
Why are there 2 diodes and how do R2 and R3 help preventing thermal runaway?
Thank you!
