Circuit Simulation in LTSpice Tutorial part 3/3

A tutorial on how to create a simulation of a common emitter amplifier in LTSpice, perform a transient analysis, tweak values, and generally do cool stuff in the simulator.

I have learned a lot watching your tutorials. You have a knack for making complex subjects easy for normal people to understand. Thanks for this one and thanks for the oscilloscope tutorials as well, a friend gave me a BK precision scope and I couldn't use it at all until I found your tutorials. Please keep up the good work and thanks again.

Let me heap praise upon you as well, I watch an Aftrotechmods video every morning before school just to get my head in the right space, I've watched some of the videos several times and always pick up something new. Wish there was some kind of award for awesomeness because you, sir would have won it a long time ago. Thanks for the great videos.

I watched this video when it came out and knew I would use the program in the future, I just used it today for some audio filtering, and it is very handy. Thank you for this tutorial, without it I'd be futzing around with the math, and not engineering the finished product.

At last! An LTspice tutorial that makes prefect sense. Please more of them. Many thanks

Afrotech, you are da MAN. Thank you so very much for taking the time and being a great teacher! Much praise to you.

No reason to close the output window between simulations, if you don't it retains the settings you've changed.

Also, you can draw lines (connections) straight through resistors and capacitors, when you press escape LTSpice removes the section going through the component. That'll speed up your drawing a lot.

Thank you for providing the LTSPICE videos. made me get up and running for my project

[johntorakis]

You are the man. Hands down the best on youtube I ever attended .. You must be some kind of teacher somewhere...

[dmxspider]

Thank you for teaching me!
I looked through my electronic textbook and found the equations for filters, some are quite complex! I made a Sallen-key type filter in LTspice, It was fun!

[boratsagdiyev]

Educational AND relaxing! What an excellent little video series. You've got a good voice there too.

[samrobinson]

All 3 videos in this series are great! Wonderful into to the software. Now, to make a real circuit behave the same way...

[ArcadeGames]

I built a time machine with this circuit and traveled back in time to 1985. Thanks!

[Insignia]

Very good videos overall! I liked this series a lot, learned quite a few useful things about LTSpice!

There is a faster way to complete your circuit wiring in LT Spice. For example at 1:05, you can start by creating a wire at the bottom node of R1 then drag the connection all the way to R2 through transistor Q1.

After you hit Escape, LT Spice will recognize the connection you're trying to make and will delete any excess wires (in this case, it will be the wire that extends from the collector and emitter terminals of Q1)

Need more! I'm learning a lot from this

[Afrotechmods]

@MudDeveloper Could be a difference between the theoretical gain and the real world gain. If the real world gain is higher, there might be clipping.

[rfinfotrader]

Hey man, I have really been enjoying your videos.

[pjharro]

Great again.

I have been using Yenka for simulating circuits, I don't know if it is as acurate as this one but has a great interface that is super easy to use. If you google Yenka and say u will only use it at home you can use it free.

I will be installing this one as well though :)

[RandyLott]

@MudDeveloper You're very welcome! I've only been using LTspice for a few weeks now, but I'm learning fairly quickly considering my electrical engineering background.

Thanks for the demo. I really appreciate this info.
