Question 1.
What is the function of a current mirror?
Show hintHide hint
Think of it as a way to 'mirror' current.
Question 2.
When discussing a common emitter amplifier, what two main currents are compared?
Show hintHide hint
Remember the relationship defined by beta (β).
3Question 3.
What is the primary purpose of a current mirror?
- To amplify voltage
- To mirror current
- To decrease resistance
Show hintHide hint
Consider what 'mirror' function entails.
4Question 4.
