LTspice tutorial - Feedback loop simulation in linear and switching systems

[@commiebobo]

Thank you, this video helped me gain enough understanding start troubleshooting a BBC design we're having trouble with.

... to _gain_ enough understanding. Hahaha, classic! I'll see myself out now.

[@kieranj67]

Thank you Fesz, much appreciated!

[@SMV1972]

Thanks for the wonderful lesson! Could you please update the link to the article by Michael Engelhardt. The link that is in the description under the video does not work

[@grigbarbulescu4218]

Great video, great explanations. Thanks

A better point to inject the sinusoidal is above the upper resistor of the voltage divider. The impedance of the ouput signal should be much higher than the impedance seen by the input signal. The load step response was not ringing so bad as the phase margin implied.

I love this channel. Telling my friends......

I'm happy to hear that, the more the merrier!

[@merden102]

Awesome...

[@IbrahimKhan-gb7wc]

when we run this example, here is the message: |1: requires a minimum of 5 parameters. Only 4 specified.

[@FesZElectronics]

The problem is in the pulse source, you need to add a 5th parameter, even if its 0;

👍

Too difficult for me for the time being, but could anybody explain me at last how recognize where in the scheme is node n004 or node n002, etc., because there is no designation of nodes in the figures presented?

[@FesZElectronics]

I'm not sure I made any reference to generic node names in this video, or was it a general question? Anyway you can go with the mouse over the desired node and LT will tell you in the bottom left corner what it's called. I do not recommend however using default node names in any measurements or formulas since these have a tendency to get renamed by LTspice - if you are particularly interested in a node (net) give it a specific name.

Alt+click the node in the plot, it will highlight the net in the schematic.
