MOSFET Amplifier Design 

Thanks for the great video. It is not common to find videos explaining how to design amplifiers with MOSFETs, in general you will find polarization analysis. To put things on the right side: when you check the value of VRD = 1/3VDD it is to confirm the voltage drop from the value of RD = 35k to ID 0.1mA, which results in VRD = 3.5V. Is correct? After all, with RD = 37.5k you get VRD = 3.75V which is close to 1/3VDD. And regarding the use of 1/2kn in the ID equation, in this case we have kn = k'n(W/L) and thus there is dependence on the MOSFET geometry. On the other hand, it is possible to use only k = ID(on)/(VGS(on) - VT)^2, where ID(on), VGS(on) and Vt are available in the datasheets.

Excellent !! Thank You !!

Thank you teacher 😊

Hats off

nice work

Very nice

Question. How did the gain go from 50 to 25 at 18:37?

You mentioned Vov=1/7 , then took Vth=1/7 V at 15:28

sir what is the bandwidth of thi amplifier? and how to calculate? and what is the voltage swing value?

Kn is 2 right why 10?

Stop writing KΩ it's kΩ. It's important because K means Kelvin (Temperature unit) but what you mean is "k" (kilo) the 1000* prefix.
