A basic CS amplifier, as shown in Fig. 3, utilizes a MOSFET with ${\mu }_n{C}_{0x}=400\mu \mathrm{A}/2$ and $W/L=10$. It is biased at $I_{D,Q}=320\mu \mathrm{A}$ and uses $R_D=10\mathrm{k}\Omega$. Find $R_{\text{in, }},A_{vo}$, and $R_{\text{out. }}$. Also, if a load resistance of $10\mathrm{k}\Omega$ is connected to the output, what overall voltage gain $G_v$ is realized? Now, if a $0.2-V$ peak sine-wave signal is required at the output, what must the peak amplitude of $V_{\text{sig }}$ be? (Ans. $\infty ,-16,10\mathrm{k}\Omega ,-8,25\mathrm{mV}$ ) 'y. 1
