Part A

Give the equation for the drain current in terms of the threshold voltage VtoVto for the cutoff region of an nn$-$channel MOSFET.

Express your answer in terms of some or all of the variables KK$,$ vGSvGS$,$ vDSvDS$,$ VtoVto, vGDvGD$.$

Part B

Choose the option that correctly describes the cutoff region.

View Available Hint$($s$)$for Part B

The cutoff region corresponds to the case in which there is no current flowing into the drain terminal because the drain$/$body junction is reverse biased by the vDSvDS source. This occurs if vGS$>$VtovGS$>$Vto.The cutoff region corresponds to the case in which there is no current flowing into the drain terminal because the drain$/$body junction is reverse biased by the vGSvGS source.
