The last circuit is a op amp made using a parametric amplifier in the first stage. There is a book called parametric amplifiers by Phillips that explains deeply and also shows this low noise parametric amplifier for low frequencies.
Hello. Almost everything you get in other simulators is possible in one way or another in LTspice. To get the FFT output, after you run a simulation, you need to right click anywhere on the waveforms window and select View-> FFT. Here you select which nodes you want to analyze (by default the plotted waves will be selected). And you get an FFt view. The more points the simulation has, the more exact the FFT view will be.
Hello, I really like your videos. I enjoy watching them. Can ı ask a question? How can we access the simulation files which you showed to us in this video as 100W.asc, 160.asc ...? Is there a fee to access these simulation files?
All these files come with the LTspice instalation. You should be able to find them either in "My documents" or where ever LTspice is installed on your PC under ..\LTspiceXVII\Examples\Educational\
@@FesZElectronics I think things have changed with the ADI takeover. I tried to reply to your reply to my comment but I think RUclips gave it the heave-ho (contained links and RUclips doesn't like that). ADI installation now uses .msi installation mechanism, and examples don't make the trip.
@@toddmarshall7573 indeed, youtube does do that to comments with links... I will try getting a new version on LT and see how it goes... anyway, did you try LT17 or LT17.1? I saw that at some point a newer version was released
@@FesZElectronics I've got 17.1.10 which is the latest. BTW: Thanks for your videos. I've learned so much that is difficult (impossible?) to claw from the documentation. BTW: Have you seen anything directed at MIDI?
@@toddmarshall7573 Its still possible to download LT17 from the ADI website - if you don't mind having both programs installed, you can use 17 just to get the example files...

Great series. Thank you very much.
7:28 BUAHAHA "What the... " I laughed very much at this, and this is a great idea to do. I'm grateful to have come across this.
How did you multiple the V(out) and I(R23)? what shortcut is that.
You can plot power by holding the Alt key and then left clicking on a component. The cursor should turn into a thermometer when its over a component.
@@FesZElectronics Thank you😄
Where do we find these examples and jigs now?
They should be in c:\..\Documents\LTspiceXVII\Examples
i want to do some fourier transform and dft , is it posible with LTSpice ?

@@FesZElectronics huge fan of urs and an electrically engineering student too, do u still see comments can u clear few doubts.
@@ayushkumar1539 usually I try to reply to comments, as much as time allows.
@@FesZElectronics glad to hear that. :) and thanks once again for this awesome tutorials..
Very informative video
can i find a pre defined circuit for rf power amplifier?
if yes then can you check the model name for me
That's awesome
