Q2 Circuit permetrs \( R_{\text {sig }}=1 \mathrm{k} \Omega \) \( R_{1}=15 \mathrm{k} \Omega \) \( R_{2}=5 \mathrm{k} \Omega \) \( R_{D}=1 \mathrm{k} \Omega \) \( R_{L}=5 \mathrm{k} \Omega \) \( V_{t}=2 \mathrm{~V} \) \( K_{n}=2 \mathrm{~mA} / \mathrm{V}^{2} \) \( V_{A}=180 \mathrm{~V} \) \( V_{D 0}=20 \mathrm{~V} \) The cupacitors \( c_{c_{1}} \& c_{c_{2}} \) are assumed to be longe \( V_{A}=180 \mathrm{~V} \) For the circuit given above a-) Draw the DC equivalent circuit and calculate the BIAs paints. Find \( V_{a s}, I_{0} \) and \( V_{D S} \), veify that the tromis tor is in SAT b-) Calculate the small signal parmeters \( 9 \mathrm{~m} \) and ro c) Draw the small signal equivalest nodel of the circuit. Replace the trinsister with its equivulent nodel. d-) Calcolute the inpt and ortput impedance of the amplifier. e) Calculate the orerall gain \( G_{v}=\frac{v_{0}}{V_{\text {sig }}} \)
