Help me !! MOSFET HW problems

[lkht]

I'm a student and im weak in electronics and electric issues ( i like computer science and programming )

I have problem and can't solve it , i tried hard but nothing solved yet

it might be easy but my mind stuck and give no solutions ..... plzz help me !! dont give me answers just the hints

problem 1

assume kn = 120 , Vtn0 = 1V , compute the input voltage value (Vin) at which the output voltage is equal to the input voltage ( Vout = Vin ) for shown circuit assuming :
1- no body effect
(w/l)up = 1 and (w/l)down = 4




problem 2

for the shown circuit , assuming kn = 120 , Vtn = 1 , kp = 40 and Vtp = -1 , compute the output voltage value (Vout)

These problems are quite easy...study basic electronics by floyd or microelectronic circuits by sedra...you will be able to solve them quite easily.

thxxx raiya ^^ ..... i checked the first book and its good

about problems i think i did not bad in solving them
