Please help with this problem. I am not sure how to even start it.

Find R?
1 (100%)
Find all w/l for mosfets?
0 (0%)

Imposed Biasing
« on: March 22, 2014, 05:20:14 am »
Hi,

I've been stuck for hours and I was hoping anyone can help. I'm not even sure how to start the problem (picture attached). 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.

1. Treat M1,2,3 as seperate circuits and find the common gate voltage required.
2. Treat Mx as an independent circuit and solve for the common gate voltage above (ohms law).

3. If they have the same mosfets, then there is a mistake also with the blue currents?
