Hi guys, I will be sharing my texas instruments Validation post interview experience.
If you have some interview experience, feel free to contact on insta I'd _trivedi_____.
If I have more questions then certainly I will try to make more such videos.
:)
Eagerly waiting for more such experiences and questions. Thanks a lot for taking time to help the students. Really helpful for the upcoming placements.
Thanks for encouraging words buddy 😊
Question 4:- not virtual short.
answer is similar as 3rd. this is very good logical question..interviewer just ask what is virtual short.there is 2 way to answer 1.some one go through your 3rd answer and 2. someone go through infinite resistance that's problem.(bcz when infinite resistance you can't apply ohms law.V=IR)when you say high resistance so no current flow so voltage is same at both node wrong explanation..and then interviewer ask two point in air and no current flow why not voltage is same everywhere?..🤔🤔🤔...simple answer is when infinite resistance no current no ohm's law so no same voltage.
and when you take open loop or comparator.problem is gain is not infinite() Vo=A(V1-V2)=Vsat....so A=Vsat/(V1-V2) Which is finite gain so put in 1st equation (V1-V2)=Vo/A(finite) this is not equal to zero.so v1 not equal to v2.so why virtual short concept is not applicable in open or saturated or positive feedback ckt.
Bhaiya, I am in B.tech 5th semester.
TI will be visiting our campus very soon for the internship program.
It will be really helpful if you bring some more sessions like this on Analog Electronics and transients.
Thank you very much.
Sure, I will be bringing some more in the coming days.
Which collage

Right now I am in 5th semester, TI is coming in 5 days, I am watching your videos and also himanshu bhaiya's video they really make very appreciable content😍😍
Hey can we connect please share any social id
in 2nd ques. i think, capacitor would neither get full charge (but capacitor will get charge more than half of the value of input) nor fully discharge
ps. : do make more contents like these , you guys are really appreciable.
I just simulated it and he drew it exactly right lol. He could have drawn the peaks a little higher but that's all
I think one way of approaching the virtual ground question would be: The negative feedback makes the amplifier closer to an ideal voltage source. Voltage-voltage feedback increases the input impedance by 1+A*beta, which is equivalent to having a (close to) ideal voltage source.
The high input impedance implies that if you feed a voltage to the terminals of the op-amp, you would be able to measure it exactly across the input terminals without any drop. This implies no current draw. Just my two cents.
This is like analog olympics. Bravo.
Now these interview videos are so much needed and is worth watching ❤️❤️❤️..thnxx
Very very helpful and loved the way you guys are telling your experiences along with suggestions
8:28 this type of plot is called “Hysteresis”
Basically, when an op amp has positive feedback, it exhibits hysteresis
Thanks, Sirs very helpful, would love more videos on interview preparation especially for the 1st mcq round like resources to study and from where to practise
Roger that
@@analogeasy-peasy7559 Yes please we have the mcq round in few days please upload video on that.
Thanl you
Great Video! and an even greater initiative!
I have a request that please discuss thoroughly till you arrive at the final answer (and what are potential mistakes one can commit) because a simple step might seem obvious to someone and maybe some other person gets totally stuck in that position. It would really go a long way to help the students. Nevertheless, the video is amazing!
Thanks for the true feedback. I really appreciate this.
So even we wanted to discuss in deep and reach to some conclusion at every possible questions but the video was going to be of 40-45 minutes, which is not so good for my RUclips channel.
So we decided to cover all questions in the faster manner.
Rest I welcome you guys to ask doubts I will surely be making videos on same in the future.
@@analogeasy-peasy7559 Even if it's longer, such detailed discussions will help others a lot. Software interview related videos are there, but finding channels like yours is difficult. Please continue your effort. This is helping us a lot sir.
Irrespective of interview experience of the candidate.what material and notes he has prepared and get ready for the interview..provide those notes and materials..it would helps us many enthusiasts.
great video guys.. bring such videos more
LPF has cutoff freq:- 0.159 Mhz.....and input signal has f= 1Mhz.....system will not allow to pass the input signal...and hence O/p = 0
First analog channel in RUclips
Please do more interviews
@@matambasavaraju3430 sure, Samsung is on the way
Hello bro,does TI conduct Off campus drive every year for analog and digital engineer role?
And what was the package at your time ?
Hi it does conduct. The package was 25 around my year.
Thank you Sir
This is very useful. But add experience for analog design roles as well. I have heard that design roles ate difficult to crack
Yep on the way.
For the last question of practical opamp, probably the interviewer wanted to listen to something like this:
Acl=Aol/(1+B*Aol)=(1/B) [B*Aol/(1+B*Aol)]= (Acl)ideal * [B*Aol/(1+B*Aol)].
Now as you had already derived (Acl)ideal=-2, so you can just tell that B=1/3 and Aol=2 (given) => B*Aol=2/3. So Acl=(-2)*(2/5)= -4/5
P.S: Here no mugged up formula has been used.
Hi @Ritayan Mitra. Here B=1/3, which is the feedback factor from output to input terminals of opamp. But why you have written (Acl)ideal = 1/B? (As ideal close loop gain is -2)
@@9935403017 Acl=Aol/(1+B*Aol). Now (Acl)ideal=Acl when Aol=infinite. So, (Acl)ideal= lim Aol->infinite 1/(1/Aol+B) =1/B
@@RitayanMitraggmu Yes that is correct, but value of 1/B is 3, right? Which suggests (Acl)ideal = 1/3? which is not giving correct result. Although, doing by conventional way is giving -4/5 as Acl.
@@9935403017 Acl(ideal) and Acl are not same. Acl(ideal) is Acl @B=infinite and Acl is Acl when B=B
Amazing and thanks
I was shortlisted for fit challenge texas instrument 2022,interview went good but still I didn't get through the technical round😕
Happens, don't worry. Just keep trying
Guys please continue the interview series
Please update more interview question video
Thnks fr this experience
Thank you
In last question we have direct formula for practical opamp gain
Right, but it's always better to know the derivation. There are different kinds of interviewer's 😄😅
Yeah right.
Very helpful
Thanks for sharing your experience. From which college you are doing Mtech?
We already did... IIT Mandi :)
@@analogeasy-peasy7559 Keep doing this work, it will help us alot.
There's one mistake that you made. When the frequency is changed to 160 kHz, then at that time the time constant becomes much less than T/2, thus the capacitor will charge and discharge completely.
Yes
No, actually for C to get completely charged, 5RC time is reqd.
Sir, How can I get internship in texas please help 🙏
Get job id by talking to people or checking out at the workday of Texas first.
Then reach out to the employees of the concerned company to get the referral.
Make more videos sir
Sure buddy
Sir aapka selection hua tha?
Nhi ^_^
What are those two guys doing in video😂 just to say ya, yes and ok
We always discuss in ourself first, then since only one has to present, others try to correct/support him.
Ps- U should be concentrating on the valuable information being given.
No offense.
@@analogeasy-peasy7559 you call this Valuable information, these stupid basic stuff I studied in my 4th semester of BTech .
P.S. just clear your basics first before creating such valueable informative video again 🤣
@@lovely_ji bro if you are intelligent then dont see the video but dont say like this .
@@lovely_ji Good for you. How about you put your mouth where your money is and get an internship at such a company?
Hello bhaiya , please tell me how can I contact u , I need some help in my project work
_trivedi_____ on insta may be, donno how helpful I could be for your project work 🥵
@@analogeasy-peasy7559 bhaiya I searched your username which u mentioned "trivedi____" but no user profile is there
Got it bhaiya
