Find the mode of its operation and the drain current in the following cases: (i) VG = 1 V and VD = 0.2 V and (ii) VG = 1 V and VD = 2 V. Key formulae: Cut-off condition VGS < Vt; current ID = 0 Linear region conditions VGS > Vt and VGD > Vt; current ID = kn′WL[(VGS − Vt)VDS − 12 VDS2] Saturation conditions VGS > Vt and VGD < Vt; current ID = 12 kn′WL(VGS − Vt)2(1 + λVDS) Solution: Case (i) VGS = and VGD = hence the mode of operation is ID = Problem 2.2: What is the mode of operation of the transistor in each of the following circuits? Take Vt = −0.8 V Note: Identify the type of the MOSFET transistor and take into account the change of the sign for all the voltages when you check the conditions for cut-off, linear mode and saturation.
