3 cards from this section. Quick, good the night before a test.
What does BJT stand for?
Think about the types of charge carriers involved.
Explain what current gain (β) represents.
It quantifies the amplifier's performance.
What does the symbol 'β' represent in BJT circuits?
It shows how effective the transistor is at amplifying.
True or False: The I-V characteristics of BJTs are linear.
Think about how diodes behave.
Calculate the collector current (IC) for a BJT with a β of 150 and a base current (IB) of 20µA. Then, discuss what this tells us about circuit design.
Apply the formula carefully and consider implications on the circuit.
Discuss how the operating point affects the performance of a BJT in a circuit. Illustrate this with a diagram.
Consider different operating regions and their effect on amplification.
