5 cards from this section. Quick, good the night before a test.
Define the term transconductance.
Consider it as a measure of efficiency in controlling current.
What happens to the operating point in a fixed bias configuration if beta increases?
Recall the definitions of operating point and saturation.
What is the impact of increasing beta in a fixed bias amplifier?
Think about the relationship between beta and saturation.
True or False: Cell bias amplifiers are unaffected by changes in beta.
Recall how 'some' changes in beta are handled.
Design a common emitter amplifier with a fixed bias. Describe the implications of a beta increase on the gain and overall performance. What adjustments would you suggest?
Consider how you could adjust components to accommodate increased beta.
Evaluate a given schematic of a common emitter cell bias design. Assess its response to beta variations and predict the operating point changes.
Analyze feedback mechanisms in the schematic.
