thanks for your effort ,but in the third problem it`s p type mosfet not n type so it`s VSG not VGS and all the calculations are wrong now please correct me if i am wrong
I believe you got the wrong drain voltage for the second question. I think it should be 0.76V. I got (3 - 0.76)V/(80*10^-6)A to get 25kOhms like you so I believe my answer is correct. Please let me know if I am wrong. Also, for #3, you wrote 0.5mA on the diagram and 0.4mA in the problem statement for Id.
@@rezuanahaque2615 if we apply voltage divider rules RG1 and RG2 then we gets 3RG1=2RG2. if we take RG1=1MOhm then RG2 Will be 3MOhm . VG=3v,Vgs=-2v then you will gets those value .if you have any questions please ask me.
Watched a lot of vids on this topic, didnt get anything. This one cleared all my doubts
Please upload more videos on MOSFET, Single Stage IC Amplifier etc.
3rd problem , i am not sure it is right??
absolutely amazing. Thank you.

just invert the Vth, so Vth=+1V, as well as the other parameters, VGS will become VSG and so on.
Hello .. How Id .4 and Rd= 5 give me Vd= .5 ?! isn't should be 2
on the 3rd problem, how did you Find Rg1 and Rg2 since the divider current was not given?
assumption based on the ratio and make current equal
thanks for the information,pls help me in how to draw small signal model from basic pls..

This doesnt help us learn when you dont show the work and when you do one of the problems incorrectly.
Thanks a lot
This was almost helpful. How about after you pause and solve, you actually show how you solved the question.... otherwise its just looking at answers
it is very helpful thanks a lot.........keep teaching
please show your work instead of just the solution. otherwise this video is useless
thank u sir
please upload more videos
Thanks man
Good video
good stuff
Why are u not solving it properly 😓
in the last math if we take RG1=2M AND RG2=3M THEN VG=2V but if we take RG1=3M AND RG2=2M then VG=3V
Can we take a random number for the current of Rg1 and Rg2?
I didn't get the solution
@@rezuanahaque2615 if we apply voltage divider rules RG1 and RG2 then we gets 3RG1=2RG2.

VG=3v,Vgs=-2v then you will gets those value .if you have any questions please ask me.
@@injamulhaque5439 if we take Rg1=1Mohm then Rg2 should be 3/2Rg1,it means 1.5Mohm ,right?then how is it 3?
@@injamulhaque5439 i got it!thank you so much for ur help
@@rezuanahaque2615 you welcome 😊☺️
