(1) (25%) Characterization of MOSFET Very small Vps ID VID 711 Slope- CW Slope CW L VIN Vos VINE Vas VINA (6) Consider an n-channel MOSFET. Its transfer characteristics are depicted above. The device parameters are W=15 um, L=2 um, and Cox = 6.9 x 10-8 F/cm². (a) Explain the corresponding operation modes for Figure (a) and Figure (b), respectively. Why do we have the totally different curves? (5%) (b) Find the inversion carrier mobility in Figure (a), by assuming that Vps = 0.10 V, Ip=35 uA at VGS 1.5 V, and ID=75 uA at Vos = 2.5 V. (10%) ©) Find the threshold Vr under item (b). (10%)
