2 cards from this section. Quick, good the night before a test.
What is the primary function of the DC bias in a common emitter amplifier?
Think about the region of operation for the BJT.
Define the superimposition principle in the context of signals.
How do AC and DC signals coexist?
What is the function of a coupling capacitor in an amplifier circuit?
Think about the functionality of capacitors in AC and DC pathways.
True or False: A common emitter amplifier's output voltage is not influenced by the DC bias.
Consider the role of biasing in circuit functionality.
Design a common emitter amplifier with specified gain and operating point. Discuss how varying the DC bias impacts performance in terms of distortion and gain.
Utilize formulas discussed in class to derive the necessary bias points.
Analyze a given input circuit diagram and identify all components relating to biasing and signal processing. Be prepared to justify the role each plays.
Look at the roles of resistors, capacitors, and the BJT in relation to AC and DC signals.
