Question 1 (15 marks) For the circuit shown in Figure 1, use a transistor equivalent circuit (either \( \pi \) or T model) to determine a) The overall voltage gain (vo/vsig) .(8 marks) b) The output resistance. (7 marks) Assume \( \mathrm{I}_{\mathrm{Q}}=2 \mathrm{~mA}, \mathrm{~V}_{\mathrm{t}}=1 \mathrm{~V}, k_{n}^{\prime}(\mathrm{W} / \mathrm{L})=2 \mathrm{~mA} / \mathrm{V}^{2}, \mathrm{~V}_{\mathrm{A}}=50 \mathrm{~V} \).
