Question 1.
What does β represent in a BJT?
Show hintHide hint
Think about amplification.
Question 2.
Name the three terminals of a BJT.
Show hintHide hint
They are the connection points for current flow.
3Question 3.
What does β signify in a BJT?
- Collector Current
- Base Current
- Current Gain Ratio
Show hintHide hint
Think about how much the signal increases.
4Question 4.
True or False: A lower β means that the transistor can amplify signals less effectively.
- True
- False
Show hintHide hint
Consider the ratios involved.
Question 5.
How would you calculate the β if the collector current in a BJT is 30 mA and the base current is 0.2 mA?
Show hintHide hint
Use the formula β = I_C/I_B.
Question 6.
A BJT with a base width of 0.1μm has a diffusion constant for electrons of 25 cm²/s. If the emitter doping is high, what factors should you consider to maximize β?
Show hintHide hint
Consider the role of charge dynamics in a BJT.
