1) in a swamped common-emiter BJT amplifier, as shown below, if Vcc =12 V, R1 =8.2 kohm, R2=10 kohm, Rc = 500 ohm, Re= 1 kohm, Vbe = 0.7 V, and B =100, what is the transistor`s emitter current?
2) in the circuit given below if R1 = 220 kohm, R2 = 56 kohm, Rc = 6.8 kohm, Re = 2.2 kohm, B= 180, or 50 kohm, C1 = C2 =10 u F, Ce = 100 u F, and Vcc = 20 V determine the voltage gain AV.
