Beautiful session ❤❤❤
Q7) for transconductance if i use (2*Id)/ (Vgst) i.e 2*4.7*10^(-5) / (1.17 - 4.7*22.7*10^(-2) comes out to be 911.73 micro S but right ans is 940 micro Siemens Does my approach is right , why is this deviation even in this year problem the deviation is same can you please elaborate sir
(2*Id)/ (Vgst) is also correct. there may be some approximation calculation of Id that is why there may be little variation. Both formulations are correct though.
@@ommaheshwari3332 ok getting, thank you for your response.
In 8 question why is the rc calculation for pole taken at input but not at the output as in case of previous question sir
rds is infinite and due to short circuit, RD is shorted, so pole at output node wont come into picture
No current flows through R2 if I am not wrong
Yes.
Si in 4 it ig gm times vin -kvout then how could you take vout common
sir pls elborate
iout = gm(Vin-k.Vout) Vout = iout x Zout Putting value of iout in above equation: Vout = gm(Vin-k.Vout) x Zout Vout = gm.Vin.Zout - gm.k.Vout.Zout Vout + gm.k.Vout.Zout = gm.Vin.Zout Vout(1+gm.k.Zout) = gm.Vin.Zout Thats how we have taken Vout common
in q 7 , why input due inverting terminal is not considered , as we already have gain A = - 10 (this year assignment), and so if we consider that case output voltage is V+(1+(Rf/Rin)) - V- (Rf/ Rin )+ offset votage why we can't consider this case
We are not supplying offset voltage as an input to R1 of inverting terminal. Offset voltage is something which is inherent in the opamp. It is like a fixed error that opamp has. Even when you dont apply any voltage to the opamp, it has an output which corresponds to a voltage difference of 1.6mV between the two input terminals. And to represent that voltage difference it is just easier to take it on the positive terminal of opamp.
@@ommaheshwari3332 Thanks for your answer, Thank you
in Q5 for calculating output impedance only R1 &R2 are known , r0 = (2/lambda*Io) or gmn= 2*(k*Id/2)^.5 but neither Io nor K or labda value are given in this question can u please elborate
Use the values given in question 1
At 47.56 mins, Id =0.0124 and not 0.12. Can you please check this?
No, it is correct, Id = 0.12mA, just to check, coefficients of quadratic equation ax^2 + bx + c = 0 are, a=8600, b=70.7106, c= -1.9. This gives x = 0.0113 and on squaring x we get Id. Edit: for current assignment value of R is 6.6k and hence Id is coming out as 0.0124 as you said. Value of R taken in problem solving session question is 8.6k.
Is there is any WhatsApp group where we discuss problem and question related to analog electronics circuit...!!
You can use the Ask a question feature on the course website on nptel. Officially there is no group in my knowledge. Students may have created unofficial groups.
hello sir , can you make a separate video for the explanation of que 8 of ass 1?
You can email me if you have doubts in that question
Can u share answers pls
Without Audio it wont be good enough, kindly fix it for next time. Tq
Sure, I will take care of it next time.
i think your voice is missing on this video
Yeah. Unfortunately audio didn't record. Please let me know if you have any doubts. You may refer to the session form other TA's for this week. I will take care of the audio next time.
