I like this one. I like especially that it stops to explain the junction bias volage and why it becomes the "diode drop" (even if it doesn't get into the implications), which is IMHO something most new people struggle with when understanding analog circuit behavior. Likewise it's careful to explain that the BJT transistor behavior is due to careful tuning of dopant levels, something that took me a long time to grok (FETs are easier to understand). The one thing I do wish it would clarify though is that this is not a FET, and it's not discussing the kind of circuits used in digital logic. These are the transistors you se in analog amplifiers and very old computers.
