Design a circuit diagram for a MOSFET biased correctly to operate in the saturation region, specifying component values and conditions.
💡 Hint: Review the characteristics and these parameters need to function in saturation.
If a certain MOSFET has L = 1 µm, W = 2 µm, V_th = 0.7V, and you apply V_GS = 2V and V_DS = 3V, calculate I_DS considering saturation conditions.
💡 Hint: Remember the significance of W, L, and V_th while calculating I_DS.
