4 cards from this section. Quick, good the night before a test.
Define a common emitter amplifier.
Think about how the input and output are connected in this amplifier.
What is the primary purpose of biasing in an amplifier?
Why do we need the transistor to stay in a specific region?
Where is the input connected in a common emitter amplifier?
Refer to the configuration of the first stage of the amplifier you learned about.
True or False: Biasing has no effect on the transistor's performance.
Consider when we talked about 'stable operation' of the amplifier.
You have a common emitter amplifier with a beta of 100. If the collector current is measured as 2 mA, calculate the base current and explain what this indicates about biasing.
Use the formula for beta to relate the currents.
Design a common emitter amplifier circuit that can handle temperature fluctuations of 20°C to 30°C. Explain your component choices.
Consider temperature ratings of components when making choices.
