Hi, Can you tell me why the SCR characteristics has negative resistance and how is it explained? I've have been searching for this explanation for a while. Thanks in advance.
Very nice explanation, Thanks a lot. I think there should be an n-well sketched, if not , reasoning for the n-diffusion which is connected to the vdd can't be satisfactorily described/reasoned for being there. Thanks again for the knowledge, your effort for making this video.
@arunkumar446 scr I-V charectaristics go linear(ohmic,increasing gm) and then take a negitive slope when latchup occurs and then I increases very drastically
Excellent description. Some moron at work designed a board to inject 5V signals into a 3.3V micro. I will send this to him to help him realise he is a clown and needs to fix it. The easiest is to put a 1R 2R volatge divider on the output.
@creativeengineer AVR's, and others I'm sure, artually have builtin clamp diodes, meaning it's actually pretty safe to connect an input of such a 3.3V device to a 5V signal. For a cool side effect of this, google "avr rfid"...
Thanks, I know you have over 200 videos now but I'm going through all of them from beginning to end. Very educational for a CpE student like me.

Thanks. I actually prefer these tutorials to product reviews, but that's just me. Thanks again.

I'm gaining an ever growing collection of bunt out components. Thanks for that advice I will try to use it well.

awesome!! are there any good books that teach practical things like this? (i.e. ground loops, burden voltages, ESD, etc.)
