hi dear all,
i am really having problem with calculating in solving cmos problems.please help me with attached problem.
best regards
 

first, the current that circulates in M4 and M6 is mirrored for M3 and M5.
 

dear jody thanks for your answer,
the main problem for me is setting dc voltage=1.65 at vo1.
 

If I4 = M * I3 and W4 = M * I3, then Vo1 should be approximately equal to the gate voltage of M4.

The VGS of M4 should be easy to calculate with the formula for current.
 

Dear Mince, thanks for your answer,
what do you mean from w4=M* I3 and what's M?
would explain more?
 

M is just a number. It should be W4 = M * W3....sorry about that.
 

Gain=10 only, why do you use this structure?
 

hello,
My main aim was learning the theoritical method for solving this circuit.
