Question 1.
What does the beta (β) of a transistor represent?
Show hintHide hint
Think about how base current and collector current relate.
Question 2.
Why is it important to assume identical transistors in a current mirror?
Show hintHide hint
Consider the implications of current matching.
3Question 3.
What is the primary function of a current mirror in an analog circuit?
- To amplify signals
- To replicate current
- To switch transistors
Show hintHide hint
Consider what role 'mirroring' plays in maintaining current.
4Question 4.
True or False: Identical transistors in a circuit are assumed to only have the same beta value.
- True
- False
Show hintHide hint
Reflect on what 'identical' implies beyond just beta.
Question 5.
Design a current mirror using transistors with given beta values and calculate the output current if the reference current is known.
Show hintHide hint
Utilize the design formulas discussed in lecture.
Question 6.
Assess the impact of neglecting base current losses in a current mirror design. What would be the real-world consequences?
Show hintHide hint
Think about how careful you need to be with assumptions in real electronics.
