Question:

Consider the common-gate circuit in Figure P7.73 with parameters $V^{+}=$ $5 \mathrm{~V}, V^{-}=-5 \mathrm{~V}, R_{S}=4 \mathrm{k} \Omega, R_{D}=2 \mathrm{k} \Omega, R_{L}=4 \mathrm{k} \Omega, R_{G}=50 \mathrm{k} \Omega$, and $R_{i}=0.5 \mathrm{k} \Omega$. The transistor parameters are: $K_{p}=1 \mathrm{~mA} / \mathrm{V}^{2}, V_{T P}=$ $-0.8 \mathrm{~V}, \lambda=0, C_{g s}=4 \mathrm{pF}$, and $C_{g d}=1 \mathrm{pF}$. Determine the upper $3 \mathrm{~dB}$ frequency and midband voltage gain.
