I watched with satisfaction the firsts 184 videos and this is the first that I found not so clear. Perhaps it is too fast and the slides parts are not strictly correlated (highlighted) with speech

I wish slides were shown for more time instead of focusing on professor.

Hello,
Thank you very much for this video, it is very informative, and I learned a lot.
I do have a question though (basic one).
In the beginning of the video you state that the jitter variance widen over time and I don't quite get it.
I understand that the phase "error" you add at each clock cycle stays there for ever, therefore over time you keep on adding errors with a given distribution.
Which means over time you have more and more chance to be really off the "ideal" edge position (vs. time).
But I don't get why the the distribution itself widens (ie. variance increases over time, t^2 in your graph)...
Can you help me understand that?
Regards.

Is there a link to the two papers by Prof Hajimiri ?

How does the formula 2D/(del_w)^2 came?

Brilliant explanation Prof Hajimiri! The explanation augments really well to the one in your paper. Thank you so much

I tried to read your paper many times, but not quite understand. Now it's clear.

Is the capital gamma function of (wo *t) the reflection coefficient of the impedance matching? If so, that woul explain that cancelling the reactive component of the negative impedance optimize to the minimum the phase noise magnitude.

Awesome, I was just getting ready to look through your lectures for one on oscillators. I was using an OpAmp as a buffer, but it started self-oscillating.

Thank you so much!!
Who can explain it better than the author himself :-)
