Consider a process technology for which Lmin $=0\mathrm{.}4$ m$,$ tox $=8$ nm$,$ n $=$

$450$ cm$2/$V $$ s$,$ and Vt $=0\mathrm{.}7$ V $.$

$($a$)$ Find Cox and k$$

n$.$

$($b$)$ For a MOSFET with W$/$L $=8$ m$/0\mathrm{.}8$ m$,$ calculate the values of VOV $,$ VGS $,$

and VDSmin needed to operate the transistor in the saturation region with

a dc current ID $=100$ A$.$
