$7\mathrm{.}21$ A CS amplifier utilizes a MOSFET biased at $I_D=0\mathrm{.}25mA$ with $V_{OV}=0\mathrm{.}25V$ and $R_D=20k.$ The amplifier is fed with a signal source having $R_{\text{v}\text{i}\text{g}}=100k,$ and a $20-k$ load is connected to the output. Find $R_{in},A_{vo,},R_o,A_{w,},$ and $G_{v,},$ If$,$ to maintain reasonable linearity, the peak of the input sine$-$wave signal is limited to $10\%$ of $2V_{ov},$ what is the peak of the sine$-$wave voltage at the output? Ans. $$;$-40\frac{V}{V}$;$20k$;$-20\frac{V}{V}$;$-20\frac{V}{V}$;$1V$
