Question $1$: MOS, solve

$V_{GS}-V_{TH}=$

The $I_D$ vs$.V_{DS}$ IV curve of a certain nMOS transistor $($with $V_{GS}-V_{TH}=2V)$ is plotted above $($solid$).$ The transistor will be loaded with $R_D=160$ and $V_{DD}=8V.$ This load line has been plotted above $($dash$-$dot$).$

What is the value of $k?$

$k=$

$m\frac{A}{V^2}$

$($within three significant digits$)$

Note that the intersection of the two curves provides the operating point of the MOSFET. What is $I_D?$

$I_D=$

$mA$

$($within two significant digits$)$
