2 cards from this section. Quick, good the night before a test.
What is the basic role of a BJT in a common emitter configuration?
Consider what the BJT does with the input signal.
State the relationship between the collector current and base current in a BJT.
Remember the relationship: I_C = β * I_B.
What happens to the collector current in a BJT as the base-emitter voltage increases?
Think about how the base-emitter junction operates.
True or False: A common emitter configuration is most often used for high-power applications.
Recall the primary purpose of common emitter setups.
Calculate the collector current if the base current is 20 µA and β is 100.
Use the relationship between collector and base current.
How would you adjust the circuit if the voltage drop across a biased resistor in the base is affecting the operating point?
Reassess the values and account for any shifts caused by the resistor.
