Question 1.
What is the purpose of a current mirror in an amplifier circuit?
Show hintHide hint
Think about current copying.
Question 2.
If I_C is 2 mA and β is 100, what is I_B?
Show hintHide hint
Use I_B = I_C/β formula.
3Question 3.
What is the primary function of a current mirror?
- To amplify voltage
- To copy current
- To provide input signals
Show hintHide hint
Think about what it needs to copy.
4Question 4.
True or False: A higher β value leads to a smaller base current.
- True
- False
Show hintHide hint
How does β relate to currents?
Question 5.
Design a common emitter amplifier with a target voltage gain of 1500 while maintaining collector current of 2 mA. What parameters will you adjust, and how?
Show hintHide hint
Assess your outputs with respect to collector and base currents' relationship.
Question 6.
If two transistors in a current mirror have a beta mismatch (β of 100 and β of 150), determine the potential impact on the output current if the bias current remains constant.
Show hintHide hint
Think about how each transistor's β influences the current relations.
