Question
In the circuit in the figure, Vi = 20 mV, VCC = 15 V, β = 110, r0 = 30 kΩ, RC = 4.7 kΩ, RF1 = 100 kΩ, RF2 = 47 kΩ. Also, since the internal resistance of the ac source is RS = 2.24 kΩ and the load connected to the output is RL = 2.9 kΩ, what is the value of the output voltage (V0)?
NOTE: The output impedance of the transistor r0 must be taken into account in the calculations.
a.
-0,62 V
b.
-1,97 V
c.
-3,52 V
d.
-1,45 V
e.
-3,00 V
f.
-2,69 V
g.
-1,04 V
h.
-2,28 V
