5. The Figure shows a discrete common-source MOSFET amplifier utilizing a drain-to-gate resistance RG for biasing purposes. The input signal vI is coupled to the gate via a large capacitor, and the output signal at the drain is coupled to the load resistance RL via another large capacitor. The transistor has Vt = 1.5V, k'n(W/L) = 0.25mA/V^2, and VA = 50V. (20 points) A. Find the DC equivalent circuit and determine its parameter B. Draw the AC equivalent circuit and Calculate: (1) small-signal voltage gain, (2) input resistance
