    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

    • @ommaheshwari3332
      @ommaheshwari3332 2 роки тому

      (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

      rds is infinite and due to short circuit, RD is shorted, so pole at output node wont come into picture

      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

    • @ommaheshwari3332
      @ommaheshwari3332 2 роки тому

      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.

    At 47.56 mins, Id =0.0124 and not 0.12. Can you please check this?

    • @rojivadiabhumitkumarr6907
      @rojivadiabhumitkumarr6907 2 роки тому

      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.
