Hello i am trying to match the following circuits OP parameters with saturation formulla.
When i looked at the parameters ,
beta=1.911*(10^-3) ( miu_0*Cox )
i put W=1u L=180n as transistor sizes.
But when i put them into the saturation state formula and tried to extract W which is in the formula X=10^-6 it gave me X=8.95326×10^-8
Where did i go wrong?
The problem is that you're using a very basic (and old) MOS equation from a text book and trying to use it with a device model that is bsim4. The text book equations do not work for a 45nm device.
Thank you very much
