The nMOS transistor in the circuit shown below has a kn = 2 mA/V2 and Vtn = 1 V. a. What is the maximum and minimum VG (gate voltage) for which the transistor operates in the saturation region? b. What is the V0 range for operation in saturation? c. Calculate the drain current ID for VG = 3 V. Hint: Part a. will help you decide the region of operation.
