I'm following this tutorial on digikey: https://forum.digikey.com/t/how-to-test-transistor-characteristics-in-ltspice/3015

Everything seems to be working, but when I insert another transistor to make it a darlington, nothing changes on the DC sweep analysis...

What gives?

Try a voltage source instead of a current source?

Q1 emitter/Q2 base shouldn't be connected to ground

Thanks!

How could I miss that?!
