For the common source amplifier in the figure below.

$($a$)$ Determine $I_{DQ}$ and $V_{DS}$

$($b$)$ Determine the voltage gain $A_V.$

NMOS

$K_n=0\mathrm{.}500m\frac{A}{V}*V$

$V_{TN}=1V$

$=\frac{0\mathrm{.}01331}{V}$

$C_1,C_2,C_3$

$R_i=1k$

$R_1=430k$

$R_2=560k$

$R_3=100k$

$R_4=20k$

$R_D=43k$

$VDD=+10V$
