Question 1.
What does 'unloaded condition' mean in the context of amplifiers?
Show hintHide hint
Think about how this affects current measurements.
Question 2.
Define current gain in your own words.
Show hintHide hint
Consider its significance in amplifier performance.
3Question 3.
What is the primary purpose of the unloaded condition in amplifier analysis?
- To increase the input voltage.
- To ensure accurate output current measurement.
- To reduce the power consumption.
Show hintHide hint
Remember what happens to the output when it's grounded.
4Question 4.
True or False: The current gain (α) of a transistor is always greater than 1.
- True
- False
Show hintHide hint
Reflect on the definitions of current gains in different configurations.
Question 5.
Design a common base amplifier circuit to achieve a current gain of approximately 0.9 with given input parameters. Explain your choices.
Show hintHide hint
Consider standard values and the relationship of components to achieve the target gain.
Question 6.
Analyze an existing amplifier design and propose modifications to improve its current gain without increasing complexity.
Show hintHide hint
Look closely at the biasing resistances and the configurations in use.
