Question 1.
Define a current mirror and its purpose.
Show hintHide hint
Consider what current mirrors stabilize.
Question 2.
What is a reference current?
Show hintHide hint
Think of it as the 'target' current.
3Question 3.
What is the primary function of a current mirror?
- To amplify voltage
- To provide stable current
- To filter signals
Show hintHide hint
Focus on stability and consistency.
4Question 4.
True or False: Early voltage is not relevant in a BJT current mirror.
- True
- False
Show hintHide hint
Think about how BJTs behave under different conditions.
Question 5.
Given a BJT current mirror where the supply voltage is 12V, the resistor is 22.8 kΩ, and reverse saturation currents are provided, calculate the expected output current.
Show hintHide hint
Break down the parameters systematically.
Question 6.
Design a BJT current mirror with a beta-helper and evaluate how the output changes when adjusting the reference current.
Show hintHide hint
Consider how base currents influence total output.
