HWN - Hardware Interviews S1E2 - OpAmps & Capacitors

Welcome back to another episode of Hardware Ninja! Ever wondered how to get a job as a Hardware Designer in some of the top tech companies like Microsoft, Google, Tesla, Apple, Facebook, etc?
The interview process employs many application based questions whether you're a recent college grad or an experienced applicant. It doesn't matter if you want to work for Elon Musk, Tim Cook, or the up and coming start-up you heard about. We're here with curated material of real life technical interview questions.
In this episode we examine a fairly common question about capacitors and op-amps. You can expect these type of questions during screenings or actual interviews

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.

[@nloko]

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!

[@HardwareNinja]

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

@@HardwareNinja So what would be the answer if the SR is infinite, but the output impedance is finite? Great channel and videos, respect!

Please upload more video like this!!

Thanks for sharing the content! Do you have sample questions RC, RL, and LC filters?

[@HardwareNinja]

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 [e-mail]

[@jogeshsingh854]

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

[@HardwareNinja]

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!

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?

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.

[@HardwareNinja]

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? :)

[@sevakantonyan9833]

Brother please ignore hatefull comments , you are doing great job and helping so much.

[@pawelstrzelecki6395]

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.
