Chapter 4, Problem 4.16P

The parameters of the circuit shown in Figure P4.15 are $V_{DD}=12\text{V}$ , $R_S=0.5\text{k}\Omega$ , $R_{in}=250\text{k}\Omega$ , and $R_L=10\text{k}\Omega$ . The transistor parameters are $V_{TN}=1.2\text{V}$ , $K_n=1.5{\text{mA/V}}^{\text{2}}$ , and $\lambda =0$ . (a) Design the circuit such that $I_{DQ}=2\text{mA}$ and $V_{DSQ}=5\text{V}$ . (b) Determine the small−signal voltage gain.
