subir fotos gratis The parameters of MOSFET: Vt=1V kn'=μCi=0.1[mA/V] λ=0.02 L=4u W=20u Here's the formula for saturation I don't know where to start and I been thinking what to do for almost 1:30 hours. I tried plugging in the values into the formula and then solving for VG to get the RG values, but that doesnt' work either. What can I do to start solving this problem? Any help would be appreciated.
From my textbook, section MOSFET Small-Signal Amplifier "RG establishes the Q-point on the load line. If we assume that v_in=V_in*sin(wt), the gate-to-source voltage will have a sinusoidal signal superimposed on the dc quiescent value. As the gate-to-source voltage changes over time, the Q-point will move up and down the line. Moving up and down the load line translates into a sinusoidal variation in the drain current." So. RG sets up the Q-point. Then everything else oscillates around that point.
No need to feel stupid. Sometimes we all need a nudge to see something that right in front of us. I've had more than my share of, "Doh!" moments and I'm sure I will have even more as my senility deepens!
