Question

#1 (30) For the transistor circuit below, with V. 012 3 45678 9 2 345 67 8 9 a) Draw four IV-curves for VG 1,2,3,4,5 b) On the left graph, find the Q-point of the transistor by using graphical load line analysis or analytically, but the grade will be 5p less. c) With this Q-point, determine if the transistor operates as amplifier or as a switch (explain). d) On the right graph, build the VTC of the transistor in this circuit using the IV curves and load line on the left plot, and indicate Q-point there. e) Bonus 3p. If the circuit is a switch, locate the second matching Qp on both graphs (explain why); if the circuit is an amplifier, find approximately its gain using VTC.
