What about the dual BJT zener clamp? They got that Vebo + Vf breakdown that would do the same thing as the diode clamp with less leakage current. It's a pretty clever way of minimizing the leakage current in high sensitivity applications while providing a fast bipolar clamp. EEVBLOG has a great video on it. Just stumbled onto your channel, I like where this is going, I'll subscribe to make sure not to miss future content like this. It's a great refresher to go back and look at these simple circuits, they never really made much sense in college because I had no idea why we needed to know this stuff.
@@TheEngineeringExperienceYT I've used it in a high voltage differential front end but I don't have a >400v source to test it's effectiveness as a camp, but I can attest to the low leakage performance. It's like the difference between C0G and other MLCC types for reducing noise in sensitive analog circuits, effectively it's a high performance cheat code you won't find in the text books.
I started learning electronics as a hobby and bought this book. Returned it the next day. I feel like it is really complicated and suited more for folks pursuing an EE degree. Lots of math and very technical.
I agree, It is a hard book to follow sometimes in which the exercises go quite heavy into maths, without much prior explanation. I have a degree and masters in Electronics and I still find it difficult sometimrs but I always wanted to develop my skills in electronics in general. Hopefully my videos make it a little bit easier, and helps people like yourself who are learning as a hobby to potentially join this growing industry. I think most of the learning from this book can be from the circuits it presents which can be really helpful. If you have any questions please let me know and I'll happy to help. I am not an expert by any means and still learning everyday. I enjoy this alot.
@@TheEngineeringExperienceYT It's a hobby I try to make time for. I work long hours. I have some other text books. Very hard for me to schedule study. Right now I'm working on my Commadore 64. Built a RF modulator kit, installed it. I now have a NTSC signal. I think my eBay special PLA was bad so I'll replace that. I like the hobby because I can lose track of time. But yes, I want to understand what I'm working with so I can trouble shoot.
Good explanation. Maybe a few xtra protection options to consider. Add a TVS diode directly on the input to protect against high voltage spikes. The breakdown voltage can be relatively high, because the diode clamp you designed will take care of any high voltage remaining. A lot of components, like a CPU, also include clamping diodes on the inputs. You can use a resistor between your output and the input of the device to have a secondary protection. Not every power supply (like a linear regulator) is capable of sinking current. So a diode clamp towards the power rail isn’t always the best solution. The Zener/diode solution you presented (in case of no negative supply) can also be used for the positive over voltage. This way the current is directly diverted to ground and does not depend on the power supply capabilities.
Thanks! And yes that's a very good addition. I made a second video with a circuit protoype and test where I go through a TVS diode as the input protection.
Just found your channel. As a hobbyists Ive started going through the AoE books I found this video very helpful and informative. can’t wait to catch up on earlier videos Keep up the excellent work 👍
Nice! I bought The AoE book (IIId edition) 3 years ago, still learning and struggling with some exercises. I also bought the "Learning the Art of Electronics" book, which is a kind of companion book (but the "hands on" lab sessions sometimes have its own quirks cause it is now near impossible to find some parts like CA3096 matched NPN/PNP transistor arrays)
If i understand your question correctly, the circuit does clip the voltage on the load. There may be various reasons you want to clip the voltage (limit voltage below adc reference, protect circuits, etc.)
@@TheEngineeringExperienceYT No my question was, in the video you described the circuit as a clamper circuit but I have studied it as clipper circuit so are these two different circuits or they are same?
If there are no answers in a book for studing a complex subject it is f.. useless to me really and I don't care who wrote the book. It is like taking the readers for complete idiots and morons. Paying so much for a book with no anwers for exercises in the book.
I agree! There should be some solutions to the questions being asked. Especially when theory behind some of the questions is not fully explained in the chapters. I think some of the reasoning behind it was for the book to be used for courses but I am not sure I buy it. It would be nice to confirm what you did for the answers was okay especially when sometimes there isn't external help available. I do like the questions as they do make you think and circuit examples and explanations are easy to understand. Generally.
Yes , exactly. For now I am studing (for my own, no university degree) from some manuals for Amator Radio Licence I purchased in France and at the same time I revise french so I am doing both electronics and french at the same time haha I gave up with the Art of Electronivs because of lack of solutions for questions there! I work full time so I can't ask anybody like students at the university..

Time to get my hands on a HV source! I'll test it out.

I picked up my copy of Art of Electronics from Goodwill for 20 bucks.
Excellent! Are you learning electronics as a hobby or career?
Hope you find my videos useful!

Subbed! Great to see that you ar doing The Art of Electoronics exercises, really helpful
Thanks!
Great video man

It is getting older now.
Thank you for making this very useful video!
Excellent video and explanation !
Thanks for watching!
very nice video! i have been working through TAOE and remember this exercise from a few weeks ago. great explanation
Thank you for watching and feedback.
I have had this idea for sooo long.. to do exercises from this book
Nice! Hope this video helps.
This is book is the best book for teaching yourself electronics, and I thank you very much for making a video about it.
Thanks!
great video. thanks!
Thank you! Glad you like it.
Which software are you using for simulating thus circuit board?
LTSpice
Form validation for hardware
How the first circuit is different from clipper?

@@marvelous2911 ah okay, that is the same thing. Clamping and clipping means essentially the same thing.
