Outstanding !! I am going through your videos regularly now. These are the real practical problems we face and somehow we know the tricks to avoid them but your in-depth analyasis help us to understand the issues and their solutions clearly. Thanks for sharing your immense experience.
Outstanding. Finally a professional level treatment of a critical topic. Mastering pages 21, et seq., is the difference between being a scientist and a slave to some gear company's marketing whank. Most TH-camrs are such slaves. Thank you for your work.
Very, very true. TH-cam is completely congested with tutorials on how to blink an LED, thinly veiled marketing materials - with much of the remainder being misinformation. The professor is one of a small number of presenters who are actually interested in teaching matters of substance. I appreciate the time you put into sharing this information with us.
Thank you professor Ben-Yaakov ! It is indeed a pleasure to read (sometimes I must re-read and study ) the professional explanations of switching power supply techniques
Hey, this is great! This is much more usefull for all kinds of problems but its from a level that there is much to learn for us! Basic things are already teached a lot on youtube but your video's are the next, more interesting level. Great again, but this second highsidescopemeasurementvideo I find even better, more usefull or more complete or, ow just more worth watching than all others i saw. A basic problem but digged deeper so this level stays alone on youtube! And i am glad i once discovered this channel!(i must say again: thanx a lot! And especially thanx for this one!)
@@sambenyaakov after making me see through my transformer-issue wich i couldnt understand since my childhood, while some others could only tell me the theoretics without making a réal clear understandable mindpicturebrealtrough, o i mean, after that its clear that you cán réally teach! Great you do it on youtube so me and many others can learn from you. I hope you can teach with these video's, spread the most possible of so much of your usefull knowledge. ( i am dutch so my english could mis the intended meaning)
Thanks for another great upload and explanation. Is there a specific datasheet or application note you are aware of that is used to teach students differential amplifiers in general within a university lab setting? I'm not looking to make a HV probe or anything. I'm just looking to test some of these concepts in a controlled setting. I have a few of TI's INA106 (differential amp with a built in resistor network gain of 10). That datasheet has several examples that could work here, but that entire datasheet is short at 6 pages. It was also first copyright in 1987 so it is as old as me. Is there a better reference you are aware of that I should look for? Thanks again for the upload. -Jake
hi, i really liked your video and i was wondering if i could use the circuit on buffer #2 as a differential voltage probe that would input voltage upto 250V from a full bridge rectifier and output 3.3v to a microcontroller?
Hello, Professor! Thank you for covering such an important topic! I want to ask a question about capacitors, which are in parallel R11,R12,R13,R14 (5:45). First time I have thought that C||R12 and C||R14 are parasitic capacitance and C||R13, C||R11 is placed there just to compensate for it. Just like in 10:1 probe in Pt.1 of your presentation. But then in a few real designs I saw all of these capacitors C||R11,12,13,14 are physically present (real capacitors). So question is follow: why do they need to put an extra capacitors at C||R12 and C||R14 if there is parasitic capacitance there anyway. Isn't enough just to put variable C||R13, C||R11 to compensate for parasitics and do not place real capacitors at C||R12 and C||R14? My guess is that they place real capacitors at C||R12 and C||R14 just to make parasitic capacitance more predictable (if Creal||R12>>Cparasitic||R12) so it should be easier to compensate for it. Thank you!
@@sambenyaakov I do have one request, could you please consider converting you many non english video to english or help provide english subtitles? I tried to understand your point by reading text and materials on slides. However I might be missing some important point as i am not able to understand the langague.
wow found out many things with this very interesting information. what kind of hobby differential probe could be designed using the: Vishay IL300 Linear Optocoupler 200kHz bandwidth, 4420VRMS isolation rated voltage , 130dB CMRejection? thank you 😎

You are someone who knows what you are talking about. It's pretty rare in the youtube now.
Thanks for kind words.
Great video, as always!

Hi, here are application notes on the web that discuss differential amplifier.
hi, i really liked your video and i was wondering if i could use the circuit on buffer #2 as a differential voltage probe that would input voltage upto 250V from a full bridge rectifier and output 3.3v to a microcontroller?
Please indicated to what minute in video you are referring to.

This a generic schematic schematics representing bot the parasitic and compensating caps.
Simply excellent.
Thanks
Excellent video sir very helpful.

This will be very difficult. I hope to eventually cover all in English version.
