Question 1.
Define α in relation to β.
Show hintHide hint
Think about how base current compares to collector current.
Question 2.
What does a decrease in W_B imply?
Show hintHide hint
Relate it to the effect of voltage on the base width.
3Question 3.
What is β in BJTs?
- Current Gain
- Voltage Drop
- Resistance
- Capacitance
Show hintHide hint
Think of the amplifying nature of BJTs.
4Question 4.
True or False: An increase in V_CB reduces the base width.
- True
- False
Show hintHide hint
Visualize the transistor's junction behavior.
Question 5.
A BJT has a β of 100, and you have an input current I_B of 10 µA. Calculate I_C and discuss the implications if the circuit operates outside the optimal biasing region.
Show hintHide hint
Consider the implications of incorrect biasing on current flow.
Question 6.
Model the impact on both I_C and W_B when V_CB is significantly increased—what happens to the dynamics within the transistor?
Show hintHide hint
Think about how the physics of semiconductor behavior changes with voltage.
