$7$: Use the following parameters for the circuit analysis: Vt $=1$V$,$ k n $($W$/$L$)=10$mA$/$V$2$ and

$=0.$ Assume Vsig is an AC souce and all transistors are in saturation.

Transistor $1$ has DC values: VGS $=9$V and ID $=0\mathrm{.}32$A

Transistor $2$ has DC values: VGS$=1\mathrm{.}18$V and ID $=162$ A

For the following hybrid$-$ small$-$signal equivalent circuit, find the following values:

$($a$)$ Rin $($input resistance specified in the schematic$)$

$($b$)$ Rout $($output resistance specified in the schematic$)$

$($c$)$ Overall voltage gain: Vo$/$Vsig $($Note: RL should be included in the gain calculation$)$
