Question

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

Step 1

To find the DC equivalent circuit, we remove all the capacitors since they act as open circuits for DC analysis. The DC equivalent circuit will only include the DC power supply \( V_{DD} \), the resistances \( R_D \), \( R_G \), and \( R_L \), and the MOSFET. Show more…
