Q: Inclusion of an emitter resistance Re reduces the variability of the gain Gv due to the inevitable wide variance in the value of β. Consider a CE amplifier operating between a signal source with Rsig =10 kΩ and a total collector resistance RC ?RL of 10 kΩ. The BJT is biased at IC = 1 mA and its β is specified to be nominally 100 but can lie in the range of 50 to 150. First determine the nominal value and the range of / Gv/ without resistance Re. Then select a value for Re that will ensure that / Gv / be within ±20% of its new nominal value. Specify the value of Re, the new nominal value of /Gv /, and the expected range of ? G
