Hi,

I've been stuck for hours and I was hoping anyone can help. I'm not even sure how to start the problem. Am I supposed to find the value of the resistor R or find different w/l values for the mosfets? How do I approach the problem? Any help is greatly appreciated. Thanks.

Using the constants given, what is your equation relating $I_D$ to $V_{GS}$?

Pretty incomplete picture.
What is the value of R?
What does "12/1" mean?
