I can't stress enough how valuable this content is for the community.

Eric Bogatin + Robert Feranec = the best of signal integrity ! thank you!!

[IanJohnstonblog]

Wow. This was such a kick ass video. Hard concepts explained in a very intuitive way.

Only 1 years with saw your all video...My Hardware Design skill made 10x better and my company when saw my hardware they made Surprised !...Thank a lot...love you...

Thank you for being such a sweet host. Thank you to the guest speaker as well; he seems like such an honestly sweet learned man. This is all very heartwarming to see such high quality lectures for free. Thank you so much 🙏🙏

An absolute magic presentation. Designing a PCB is not a simple task as many may think. The schematic is the easiest part. Selecting auto route is probably the worst mistake when working with high frequency signals. There are valid reasons why different PCB materials exist.
Thank you, this is a fascinating field on it’s own.

Bogatin is the man! Great choice of guest. 👍

I thought I knew how to layout a board because I've been gaining experience, but this video shows me how little I know, so far. Thanks for giving me something to sink my teeth into. This is the most important layout video subject matter I've been able to find. I now need to produce a new better layout for my PCB project, after seeing this.

Food for thought. One thing you can do to fix a GND return gap, or say if you MUST run a trace over 2 different GNDs, or power planes, is you can couple them together with a capacitor. You essentially provide a High Frequency path for the return current to pass through the gap. It keeps DC from moving between, but allows the return current to continue to follow underneath the sharp edge transition of your positive signal.

"Signal integrity lives in the white space of your schematic."

Damn.

Fourier would be so proud to see these videos.

I think this channel is very under-rated. The information I learned from you are very practical.

35:35 Took the rabbit trail to HFSS Simulation and found ANSYS Software. Mind blowing capability, WOW !
My new acquisition and proficiency goal for System Integration of projects. Still newbie, but seems cutting edge powerful to assist designs.
I'm particularly thankful for your introduction to Eric Bogatin.In addition to your channel, my path forward certainly now includes :
The Signal Integrity Academy. Double thumbs UP ! Thanks and Regards !

Absolutely fascinating! Anytime two great engineers have a discussions like this, we're going to learn a lot.

[patrikstaron]

I had this idea in mind since I was 15 years old and told myself that the voltage must gradually get throuth the conductor, not magically be there all at once. Now I finally see the details.

[glenmartin]

Thank you both.
Much of this was over my head, but it helped me understand the complexities of designing PCBs and not garbling a signal.
Thanks, again.

[Detroit_Playa]

Hobbyist here thank you for the info I've never been to school everything is self taught and videos like this are invaluable to someone like me. You guys are talking about stuff I've never even thought of but now that I've seen it that image of running returns over gaps and all the static will never leave my brain after this. When I'm making pcb's in the future I will apply all of this thank you.

[burievsardor]

It is difficult to believe that such kind of videos are now available for free. Thanks a lot, Robert. Now because of you i know who is Eric Bogatin.

[jarvenpaajani]

This is really good. I actually have been struggling implementing 10/100 mbps ethernet with RMII and this video made me realize few bad design decisions on my latest board. Subscribed!

[awdheshkumarmrt]

Thanks Eric. I enjoyed learning about how we have to dive deeper into the concept of fields to understand the return currents.

[danthomas]

It was very helpful with your pauses in the video to give clarifications, Robert! Thank you!
