A MOSFET is biased with V_GS at 5V. Given K=0.5 and V_th at 1V, find I_DS when in saturation. Assume V_DS=10V.
💡 Hint: Focus on the relationship for I_DS in the saturation region.
If a common-source amplifier developed an output voltage of 2V with an I_DS of 5mA flowing, what is the drain resistor value?
💡 Hint: Connect how voltage drop across the resistor impacts the output voltage.
