A standard MOSFET is fabricated with fms=-0.89V, Qi=5e10 q/cm2, d=500?, A (gate area)=1e-3 cm2, and NA=1e15 cm-3 Assume T=300K, the flat band voltage VFB and the threshold voltage VT are -1.01V and -0.21V, respectively. At VG-VT=3V and VD=1V the MOSFET exhibits a drain current of ID=2.5e-4 amp. Please determine the drain current if VG-VT=3V and VD=4V.
A、3.5e-4 amp
B、4.0e-4 amp
C、4.5e-4 amp
D、1.0e-3 amp
