Find the low$-$frequency gain and high$-$frequency gain of the next circuit, and the zero and pole frequencies $($where the frequency is $(ra\frac{d}{sec}).$

$I_{\text{D}\text{m}\text{a}\text{t}}=K(V_{GS}-V_T{)}^2,K=\frac{1}{2}{C}_{as}(\frac{W}{L})$

$I_{D,\text{i}\text{n}\text{i}\text{n}}=K[2(V_{CS}-V_T)V_{DS}-V_{DS}^2],K=\frac{1}{2}{C}_{as}(\frac{W}{L})$

$g_m=2K(V_{GS}-V_T)=2\sqrt[\phantom{2}]{K*I_D}$

$K_p=K_n=1[\frac{mA}{V^2}],V_{TP}=-1[V],V_{TV}=1[V]$
