Excellent video, when you say active region of the MOSFET are you refering to triode region? Thanks

I think you made a mistake at 17:27 , it should be gm=2/Rp

Thank you very much for the videos Susanta. I tried making excel sheet by my own and really helped me in total understanding of the two videos you posted on LC VCO.

wondering about the 7dB he is adding to ADC op dBm: Pin dBm =10log( (V^2(rms)/R*1000) ) = 10log(Vp^2 * 1000/(2*100) ) = 10log(Vp^2) + 10log(1000/200) = 20log(Vp) + 7dB

at 52:35, why the Av is sqrt(L/C)/50 ?

Hi Susanta, we havent heard you in last 5+ yrs. Please upload more video on latest technology, IC sub block designs etc. Hope we will listen once again.

Hello Sir, I have a doubt. What if we skip the cap bank and use only the mos varactor. How will it affect the circuit?

What does ACPR stand for?

@socialogic9777 Жыл бұрын

I watched this over 4 days and it was so much worth it. The intuitive techniques are a necessity when getting lost in long derivations and unable to interpret the results is a reality.

AC ground gets created due to splitting of vin at 3:03:36, i didn't understand?

@utubevenky Жыл бұрын

yes the common node doesnt see any "ac signal" or small signal, in other words even in AC or tran analysis it will remain in the same voltage(= the DC voltage) that you see in the operating point analysis

Thanks for valuable info sir (at free of cost)...Those who are having little bit knowledge about MOSFET , Cadence & Op-amp design ...then they will definitely fall in love with ur teaching ...just like me...

How come cdso is from drain to gate ? Shouldnt it be cgd ?

Also, are you sure the expression you arrive at in 3:39:14 for the zero frequency is correct? Most analyses I've seen of the frequency response of the 5T OTA place the zero at ~ -2gm5/C2; i.e., twice the mirror pole frequency, *and at the LHP*, not RHP.

Dear Sir, thank you for sharing knowledge, and for the excellent method of delivery. Minor notice: From 2:58:16 onwards as you showcase the differential amplifier schematics; it is important to note that your output nodes' polarities should be reversed. Your diff pair devices are still common source amplifiers, so it stands to reason that the polarity of output node at D of device will be of opposite phase to input at G of device.

can you please tell me when you calculate the Rp you do not enter the unit scale values like (Ghz,nH etc) .what was the reasons.

This video is a GEM. The lecture notes look a lot like how Prof. Asad Abidi teaches analog circuits!

@LightningHelix101 2 жыл бұрын

Thank you for sharing your notes and talking through them. So many resources focus on the multitude of possible schematics that the details get disjointed across the entire piece of literature if they are included.

Hi Susanta, these lectures are so great, thanks a lot for you effort, i wish you can post some more videos or please direct me to some material you wrote, like the TX chain maybe some ADC aliasing and other. again thanks you very much
