Always good to understand circuit theory from a slightly different perspective than the usual explanations. I've had many explanations of this since I first encountered transistors in the 1960s, but Ralph's was still informative.
YT just fed me your previous video and now I am subscribed. I started my EE design career 34 years ago but quickly fell into software development instead. I am very interested in what this channel could get into. Thanks for your efforts.
That is a very common thing to happen to EEs. I resisted that and remained primarily a hardware engineer throughout my career. However, now a days nearly EVERYTHING has some sort of processor embedded in it, so I did a LOT of embedded processor firmware (C) as well as programmable logic devices (VHDL). But my first love was always the hardware. I am glad to have you on board! 🙂
EXCELLENT PRESENTATION!ONE OTHER CHARACTERESTIC IS IT IS GOOD AT RF APLICATIONS.IT WOULD INTERESTING TO SEE THE RESULTS WITH AN AC SIGNAL THROUGH THE CIRCUIT.
Never really understood this circuit or why one would even use it. I guess I would ask how does it perform over temperature? is it now only having voltage dependancy on the vbe temperature coefficient?
As I have understood it, it performs well over temperature and avoids certain issues that other configurations have to deal with; which ones I am a loss to remember at the moment. Because it has voltage gain but not current gain, it is often used as a power amplifier. Same current in as out, but higher voltage = power increase. One could put a circuit such as this in LTSpice and tell LTSpice to step over temperature to see its response. 🙂

Thanks! 🙂

You make learning easy and fun! A lot can be learned by implementing these "basic" circuits. I love your approach to teaching thanks and tootaloots!
Wow! What an encouragement! 🙂 You are very welcome!🤓
What a fantastic experiment .
Thanks! 🙂
Another great video I've learned so much watching this series. Thanks again Ralph.
Thanks, man! ... and you are welcome! I have the first Beta Stable video rendering as I type for release next Wednesday. :-)
👍Thank you sir.
You are welcome! :-)

Thank you! Yes, it would. The next step would be A.C. analysis which I cover in the videos on load lines. 🙂
