7.1.1. Lecture - 07

Try these first

1. 1.

   What does BJT stand for?

   Hint

   Consider the types of charge carriers used.

2. 2.

   What happens to the current in a forward-biased junction?

   Hint

   Think about how voltage affects diode behaviors.

3. 3.

   When a BJT is forward biased, what happens to the current?

   • It decreases
   • It stays the same
   • It increases

   Hint

   Think about the behavior of springs with added tension.

4. 4.

   The two junctions of a BJT interact with each other. Is this statement True or False?

   • True
   • False

   Hint

   Consider how electrical paths can conflict.

5. 5.

   Consider a BJT where the base-emitter junction is forward biased with 0.7V. Calculate the expected increment in current if it is initially 1mA.

   Hint

   Incorporate how exponential functions variables interact.

6. 6.

   Design a simple amplifier circuit using a BJT. Describe how you would determine the values for resistors used to control the base current.

   Hint

   Connect resistor values to current requirements with proper circuit analysis.
