If you do a search for a current mirror on the web, you'll probably find this one. The problem is that it doesn't work as drawn. I take a look at the circuit and show you one way to fix it.
Welcome back, and thank you. Also, I had already burnt up a few 2n2222 transistors following the others presentations. Dropped it as it did take some time just to match the betas. This helps greatly on understanding it.
I remeber my uni professor explaining the effect of early volatge being the figure of merit of a current mirror but never really got it untill now thanks great vid!.
you explain very nicely please some vintage test equipment like vom, vtvm, tvm construction working principles possibly restoration, not find on internet :)
