ExercisesR C5 KΩ12 VV CCCB I BI CV CV SR BV BEEV BI EV ER E3 KΩ9. For an NPN transistor circuit β = 100 , V CC = 11.3 V , V B = 3.5 V <strong>and</strong> with the reverse−biased collector−base junction set at V CB = 1.8 V we want the collector current to beI C = 0.8 mA . What should the values of R C <strong>and</strong> R E be to achieve this value?10. For a PNP transistor circuit with β = 120 , V EE = 12 V , V B = 0 V, V CC = – 12 V , <strong>and</strong>R E = 3 KΩ , what would the largest value of R C be so that the transistor operates at theactive mode?11. For a PNP transistor circuit with β = 150 , V EE = 12 V , V B = 0 V, V CC = – 12 V ,I E = 0.8 mA , <strong>and</strong> V CB = – 3 V, what should the values of R C <strong>and</strong> R E be so that the transistoroperates at the active mode?12. For the circuit below, it is known that β = 120 for both transistors. Find all indicated voltages<strong>and</strong> currents. Are both the transistors operating in the active mode?
