Question 1.
What is the purpose of a current mirror?
Show hintHide hint
Think about how this impacts signal processing.
Question 2.
What is the collector current (Ic) in our example?
Show hintHide hint
Refer to the desired current stated in the section.
3Question 3.
What is the main function of a current mirror?
- To amplify voltage
- To maintain a constant current
- To reduce noise
Show hintHide hint
Think about how a mirror works in real life.
4Question 4.
True or False: Mismatched transistors in a current mirror will lead to accurate current replication.
- True
- False
Show hintHide hint
Recall the definition and purpose of current mirrors.
Question 5.
A current mirror circuit requires a collector current of 5 mA. If the β of all transistors is 150 and base current is considered non-negligible, calculate the required bias resistance.
Show hintHide hint
Remember to account for base current in your calculations.
Question 6.
An amplifier circuit with a nominal input voltage of 0.5V, output voltage gain of 1000, determines the corresponding output voltage.
Show hintHide hint
Notice how the gain impacts the output voltage significantly.
