$10\mathrm{.}36$ Consider a p$-$channel MOSFET with the following parameters: kp $0\mathrm{.}12$ mA$/$V$2$

and WL $20.$ The drain current is $100$ A with applied voltages of VSG $0,$

VBS $0,$ and VSD $1\mathrm{.}0$ V$.($a$)$ Determine the VT value. $($b$)$ Determine the drain

current ID for VSG $0\mathrm{.}4$ V$,$ VSB $0,$ and VSD $1\mathrm{.}5$ V$.($c$)$ What is the value of ID for

VSG $0\mathrm{.}6$ V$,$ VSB $0,$ and VSD $0\mathrm{.}15$ V$?$
