For the FET circuit in Figure P7.63, the transistor parameters are: \(K_{n}=\) \(1 \mathrm{~mA} / \mathrm{V}^{2}, V_{T N}=2 \mathrm{~V}, \lambda=0, C_{g s}=50 \mathrm{fF}\), and \(C_{g d}=8 \mathrm{fF}\).

(a) Draw the simplified high-frequency equivalent circuit.

(b) Calculate the equivalent Miller capacitance.

(c) Determine the upper \(3 \mathrm{~dB}\) frequency for the small signal voltage gain and find the midband voltage gain.
