In this video, Gregory unfolds the behavior of the PLL - Phase Locked Loop, explaining how it works and the role of the loop filter.
The PLL is analyzed in the phase domain, as a closed loop system. A bode plot is used to show the behavior of the lead compensator, that increases phase-margin and guarantees the loop stability.
The PLL described in the video is part of the 10GHz Source project that is being developed on the channel:

This is the best explanation of a loop filter I have ever seen. Not only pure theoretical, but with a practical switch, which makes it easier to grasp.

After watching this, now I understand how VCO vs low pass filter matters. Thank you GREAT TEACHER!

I'm not a regular youtube commenter, but I feel like I really have to in this case. I follow your channel closely, your videos are very valuable to me. They provide a lot of theoretical insight, yet are practical enough to not forget why you are explaining/learning this. I also like that you take the time to explain things very thoroughly, making things look very simple even though I wouldn't even know where to start when researching these things myself. I hope you keep on producing these nice videos!

This video is fantastic--thank you so much! I love how you explain the fact that the VCO is an integrator for the phase!

I totally agree with the other commenters You did a great job with your explanation. I like how you didn't just start in the phase domain. It makes sense to look at PLLs in the phase domain but I personally find it rather unintuitive so starting in the frequency domain made it very clear for me. I recently experimented with adding an adder in the loop filter and adding on an audio signal to implement FM modulation. It was quite interesting to get it stable but it worked out pretty well in the end. Looking forward to the next part, generating the actual circuit from a high level control model like this is another quite complex task.

I always wondered really what was meant by Phase Margin in a loop filter...you made this so clear in this video, thanks for the lesson -I'm now subscribe and your English is fantastic to me; keep em coming.

Very nicely explained the role of the zero!!! I came to your videos while I was troubleshooting spurs of my PLL. Looking forward to videos on bandwidth vs noise of all kinds and lock time. Keep up the good work Sir!

Simply excelent! I thought that the second capacitor added at min 24 was already take it in account on the phase detector transfer.
@AllElectronicsChannel

Thanks! If you think that the transfer function of the filter is from current to voltage, you will see that in both cases (only the capacitor, or the lead compensator) have the 40db/dec at lower frequencies (pole at 0Hz)

I like how you pronounce error hhh. I like how you try so hard and repeat yoursel over and over to explain and give the audience a chance to digest the idea. I also understand english isn't your native language so it's hard for you to express your ideas easily. overall I like your sharing your projects. thanks.

You trying to correct someone else's pronunciation(I am glad you did because I didn't understand what he was saying!!!), but you also made "a-hor" on your spelling of "yousel" instead of "yourself".
