Dear prof. Yaakov, thank you. All your videos are of outstanding quality, but this presentation was even better. Im doing EMC design in automotive for a living and basically EVERY sentence you have said describes some issue that already happened either in the field or during the design validations. Anyway in best case resulting "only" in tenths of thousand dolars investigations. Your videos should play in infinite loop on every HW department :) Thank you for the content and wish you marry Christmas and happy new year!
Your videos teach some of the same techniques I learned from working with people in aerospace that do power electronics. Thank you for sharing your knowledge!
This is on point! Can you please direct me to the video where you had discussed "Why bootstrap is not good enough especially in GaN"? Thanks for your outstanding lectures.
problems?! 1. The high frequencies would get past most LDOs, assume you ignore that 2. since LDOs should also have input and output capacitors, you can consider it as another dc/dc, which can have the same problem as the original DC/DC
Well, I had assumed that people will pick up the torch from here.. The objective of the LDO is to handle the DC. The AC can be easily attenuated by ferrite bead or inductor,
@Fred Garvin 1. capacitance leakage between input and output, LDOs have much larger leakage at HF 2. control loop frequency of LDO is limited, the control loop of LDO which rejects Power supply variations is useless above certain frequency
@@sambenyaakov There is an impedance between two ground points but is the ac current (Iac) returning to the power supply ground mostly due to IC (high-frequency current) or power supply ripple?

Thanks for you kind note. Comments like yours keep me going.
I consider this one of your best videos because it's relatively short, to the point, without mathematical formulas making it more complicated.
Thanks. In as much that I a proponent of the intuitive approach, sometimes you can't escape mathematical formulas😊

Thanks. Well, these idea have also been used on earth😊
Your videos are like my treasure that I don't want share anybody. Hope you sir have the very best of holidays.
Thanks😊
thanks again
the truth sets you free
😊
I liked this one very much, I had not thought about that loop current before. Thank you.
Thanks for note
Amazing videos as always. Thank you so much for sharing your knowledge!!!
Thanks for comment.

Sorry, just realized that this issue was touched in a live lecture in Hebrew. Here is the link

Will you make separate playlists for all your videos to organize them?
Too complicated. You can reach my video on a certain subjects by typing in TH-cam search window: "sam ben-yaakov subject"
Hi Sam. Any book about this subjetc? This is very interesting 👌🏼
Not that I know of.

@Fred Garvin nothing is immune to high frequencies mate, LDO's PSRR is good till certain frequencies.
@Fred Garvin 1. capacitance leakage between input and output, LDOs have much larger leakage at HF
2. control loop frequency of LDO is limited,
the control loop of LDO which rejects Power supply variations is useless above certain frequency
Hello, professor, could you share your knowledge about current transformers, in no-measuring applications?
Have you seen th-cam.com/video/-hwnGHOe9f8/w-d-xo.html
In the connecting to power supply slide, what generates the ac noise signal (VG) between two grounds?
The fact that the tow ground connection are not at the same point and that there is a voltage drop in a ground plane
@@sambenyaakov There is an impedance between two ground points but is the ac current (Iac) returning to the power supply ground mostly due to IC (high-frequency current) or power supply ripple?
@@fanshengshi1505 It will be primarily due to the main transistors switching current
@@sambenyaakov thanks you very much professor Ben Yaakov!
🙏🙏🙏❤️❤️❤️🙏🙏🙏

Hi sir please suggest a book for to learn about more basics of MOSFET and power electronics.....from basic s ....I am ready to pay to buy the book
Sorry, I am not updated on recent books
