Your Videos are a pure source of knowledge. Thanks for sharing.
Thank you very much for nice words
Good video and nice presentation with demos. I recommend Arthur Kay's book about Op Amp Noise for practical engineers.
However, I think we miss a very important part of op amp topic, which is the modeling of the op amp. Think about modeling of the noise sources, CMRR, PSRR, slew rate, input impedance, and output impedance.
I always get quality knowledge from this channel. Keep it up. God bless you ❤
Great lecture, thank you!
Great video! One request Make this kind of video for every circuit element. That would be great
thank you. this is on my todo list. the hard part is finding people. so if anyone knows some very good engineers who would like to talk about these topics, please send me an email or message on linked in.
This is fantastic video. I have learnt many by this video. Thank you❤
That's some high quality content and perfect to complement my reading of Chapter 4 of Art of Electronics
Fantastic video!
A lot of useful information in this video Robert. Must watch before dealing with op amps. I'm just in the process for selecting proper op amps for my electronic load(i think i'm choosing opa189).
Thank you. Very good Video !!!
Nice informative
OPA928 is a competative of the long out-standing ADA4530-1, which appeared roughly in 2016. And TI even made it pin to pin compatible to ADA4530-1, with the same guard ring structure.
subscribed, and liked the vid, thanks.
Everything thing about op-amps is mathematics related, its invention by design was for a analog computers part #741, so the first topic out the door is DC again and DC feedback, advance topics are AC parameters this is where we enter the upside down world TYPE-1,2 and 3 compensators and beyond.
Wow ! Thanks Robert but you are upsetting Netflix/Prime by releasing this video on Friday.. their no of viewers is getting down because of you😅
:D
@@RobertFeranec request you to make detailed video on SMPS magnetics design.. please please
Thanks! It was pretty theoretical right from university, I don't know something is missing. The part of stability was nice (don't put capacitor directly to opamp output) and for guarding. I think I am missing some practical solutions for low voltage signals. ECG, Potentiostat, Strain Gauge. These are pretty common applications where you can describe small lifehacks and tradeoffs with opamps regarding their parameters schematic and layout.
And maybe for this I would ask AD guys (sorry TI you are good for high power)
Thx. Please do you have any contacts in AD?
@@RobertFeranecI have, but I am not sure they are better than yours =) As HW engineer I work not with best lectors, but with other engineers. Also with AD there is a problem, once you get to something interesting they force you to sign NDA. No offense Robert, You do your best. It is because usually you provide something mindblowing this one didn't really catch me.
@@RobertFeranec Also Robert, in TI they recently introduced pretty interesting LED driver LP5813. It is matrix, with Autonomous (no need constant I2C polling), integrated high efficient boost, 0.1uA sleep, small like 2x3mm and cost 0.3USD. I start putting this driver any battery operated project.
HI Robert,
I am currently working on projects involving the design of electronic circuits for Atex products. Would it be possible for you to create a video addressing this specific topic? I am confident that your expertise would be of great help to me and others in the field.
Can we download the presentation somewhere?
At 1hr4min where did the 1.57 number come from?
What is phase margin? Can someone explain in simple terms?
do instrumentational amplifyers
This works like a lever isn't?
We need LED PCB design
What is about LED so specific that you need video?
My company is LED street light , flood light manufacturing company so I need altium design in led video
Sir please send me the LED PCB design
