Need 100s of videos like this. I feel like I have forgotten most of the stuff working only in semi branch solving basic stuff related to the application. Tnx for sharing
For the last question, instead of SR the more correct answer in this case would be to talk about output impedance; SR is pretty much a byproduct, also it's only specified for a limited max capacitive load which could be smaller than your "unknown" C.
And also ask the interviewer how it is possible to have infinite bandwidth with limited slew rate! It'll show you know how all those values interact with each other and where they come from!
Hi! Thank you so much for contributing to the discussion and for being a part of the community! Slew Rate is not a byproduct of output impedance (ideally zero for an opamp). Output impedance of the opamp is a byproduct of infinite gain (i.e. output impedance of the transistors divided by the loop gain). However, gain and also output impedance assumes a small signal model (i.e. the system is linear). During a transient, when the amplifier slews, the linearity assumption is broken. That's the reason they're not related. We hope that sheds some light on the topic. If you have any feedback or we are mistaken please do let us know! Cheers
Thanks for your comment and support! We will be getting into filters in a few weeks. But if you're interested in the questions alone, send us a message at hardware.interviews@gmail.com
Generally speaking do interviewers respond better to being asked what kind of assumptions can be made? Or do they prefer that you confidently assert your own assumptions?
Hi Jogesh, While these are analog in nature, they also apply to hardware in general. We will be coming up with some digital questions soon. Stay tuned and thank you so much for the support!
We're sorry you find the accent "irritating". It is our hope that people focus in the content itself rather than an accent. Besides, aren't all accents fake? :)

@@HardwareNinja So what would be the answer if the SR is infinite, but the output impedance is finite? Great channel and videos, respect!
Thanks for sharing the content! Do you have sample questions RC, RL, and LC filters?

Please upload more video like this!!

Pretty well.👍🏼👍🏼
Are these analog design questions ?could you bring up more about digital design too?

need 100 💯 ok video like this i feel like I have forgotten most of the stuff working only
🍿🍿
Why fake US accent? It's irritating.

Brother please ignore hatefull comments , you are doing great job and helping so much.
I don't find it irritating, in fact I find it pleasant and clear to understand. I have no clue if it's US accent, fake US, and I don't really care.
