Sorry if this is in the wrong section, it is my first post
anyways back to the question, actually heres a picture of the problem.
i calculated unCoxW/L for Q1 to be 960uA/V2 and unCoxW/L for Q2 to be 240uA/V2
now im having trouble/forgot how to find the mode of operation for when there are two in series. i was thinking that for Q1, Vdrain= 1.5v Vsource= 0V and Vgate = 1.5v
but then again i could be completely wrong, i just need help with finding which mode it is in.
Both the transistors are in the saturation region as in both cases Vgs> Vt and Vgs=Vds. Value of resistance is 12.5 K
Here you can use simple Ohm's law. V=IR Voltage across resistance is 5.0-3.5= 1.5V I=120uA Hence R=12.5K
