how do you know to measure the transconductance at the voltage point you set vgs to be ? Why didnt you look at the point at which the derivative graph peaks as that would give the maximum transconductance?

[@shreyanshujaiswal204]

Which one is more accurate value of gm , the one we get by calculating on calculator or the one in annotations ( dummy analysis) ?

[@anarghyabg4342]

Hello, the question i am asking is slightly relevant i think, can we plot the VTC for Cmos Inverter for βn/βp = 1, 3, and 5 ratios on the same graph?

Thank you for the video. Is the process of simulation in tsmc and umc same as in gpdk??

[@shruthis9465]

Hi your videos are helping me a lot.

[@vlsiforrookies]

Thanks, glad to hear that

[@theminertom11551]

I think that this course would be fascinating if it were in a language that I understood. I apologize for that. Simply having captions available would be a great start.

He is mixing Indian with English which is kind of weird isn't it ?

[@todayiwill1361]

Yes a lot ahahaha

[@bharatsaini-qf6zz]

Sir I completed my btech in electronics and communication engineering in 2020. Sir I want to make career in VLSI industry. Is it possible after 3 years gap.if yes sir please suggest way to make it .

[@IITMIAN_ABHILASH]

Thank you so much......

[@annguyenvan6560]

How can I install gpdk180? I am a college student so could you share this for academic propose?

[@kishanbhojrath2755]

i want to know the same...i have gpdk90 only

[@amitkumar-sh2lk]

thanks bro. but i have one doubt. why most youtubers teach in gpdk. we have tsmc pdk in our college

[@arunpandian294]

Well, TSMC pdks are confidential and are not allowed to be shared with others. Colleges have them because they have a form of tie up with said foundry, who in turn provide their pdks for learning purpose.

@@SahanaKolur-lk3tc Yes it should have the same procedure, the technology from foundries have additional parameters for different device models. If your intent is to do basic designs and learn the fundamentals then you will apply same concepts as shown here.
