4 cards from this section. Quick, good the night before a test.
What does it mean for an amplifier to be in an unloaded condition?
Think about how grounding affects the output.
What is the typical range of current gain (alpha) in a common base transistor?
Consider the efficiency of the transistor's function.
What happens when a common base amplifier is in an unloaded condition?
Think about grounding in AC circuits.
The current gain in a common base configuration is generally greater than 1.
Recall the characteristics of transistor amplification.
A common base amplifier circuit has an input current of 500μA and yields an output current of 475μA. Calculate the current gain and discuss whether this amplifier is effective for applications requiring high precision.
Consider again what the desired levels of accuracy and performance might be in practical situations.
Design a practical application of a common gate amplifier in an RF system; explain how to choose components and biasing conditions to ensure good performance.
Focus on finding components that ensure the operational frequency is aligned with RF requirements.
