Ap-channel enhancement-mode mosfet with 50 nm thick hfo2 high-k gate dielectric (εr=25) has a threshold voltage of -0.6v. the effective hole channel mobility is 150 cm2 /v-s. what is the drive current for a 50 μm wide and 2 μm long device at vg= -3v and vd= -0.05v? what is the saturation current at this gate bias?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
