9.2. BJT Characteristics

Try these first

1. 1.

   What does the term I-V characteristic refer to?

   Hint

   Consider the basic definitions of current and voltage.

2. 2.

   What is the importance of biasing in a BJT?

   Hint

   Think about how BJTs amplify signals.

3. 3.

   What does β (beta) represent in a BJT?

   • Collector current to base current ratio
   • Base current to collector current ratio
   • Emitter current to base current ratio

   Hint

   Focus on the current relationships in BJTs.

4. 4.

   True or False: The saturation region of a BJT allows for linear amplification.

   • True
   • False

   Hint

   Recall definitions of each operational region.

5. 5.

   A BJT has β = 120, and you want a collector current of 600 mA. What should the base current be?

   Hint

   Use the relationship between collector current and base current.

6. 6.

   If the temperature of a BJT increases significantly, how would this affect its I-V characteristics?

   Hint

   Consider the effect of temperature on semiconductor properties.
