Transistor Circuit Analysis


Posted on Feb 5, 2014

The schematic is this fairly simple transistor circuit: Seeing schematics with transistors in them brings back a flood of memories to my college days when I was taking EE classes and I used to know how to do this stuff in my sleep. Unfortunately, that was about 15 years ago, and now a schematic like that looks like gibberish. It was bugging me that I used

to be able to figure this stuff out, so I pulled out my old textbooks. Those were nearly as incomprehensible as the schematic, unfortunately. Luckily we have teh internets these days, and I found instructions on transistor circuit analysis that I could actually understand on the website for EECS 312 at the University of Kansas. Kudos to Prof. Stiles for making this understandable. This transistor is in saturation mode, and I calculated the emitter voltage to be about 2. 7 V. I measured the voltage drop to be 2. 72 V with the scope, which you can see on the right side of the scope`s screen in this picture. It`s nice when theory and practice align. It`s even nicer when I don`t have to show my work.
