Step 1 of 3 5.005E The device transconductance parameter kn is, Here, is the mobility of electrons and is the oxide capacitance The linear resistance is, Substitute 1 kΩ for and 0.5 V for in the equation. Hence, the value of transconductance parameter is Step 2 of 3 When the voltage VDS is increased to then So, the transistor operates at the edge of saturation. The relation for the drain current is, Substitute 2 mA/V² for , 0.5 V for , and 0.5 V for in the equation. = 0.25 mA Hence, the value of drain current, when the voltage is increased to 0.5 V is, Step 3 of 3 When the voltage is increased to then > So, the transistor operates in saturation. The relation for the drain current is, Substitute 2 mA/V² for , 0.5 V for , and 0.5 V for VDs in the equation. = = 0.25 mA Hence, the value of drain current, when the voltage is increased to 1 V is, When transistor is operating in saturation, the drain current is which is independent of So, the drain current remains same even when the increases.
