Question 1.
What is the primary purpose of a current mirror?
Show hintHide hint
Think about the role of stability in circuit design.
Question 2.
In a common collector amplifier, what is the main design benefit?
Show hintHide hint
Consider how the input and output signals relate.
3Question 3.
What is the role of a current mirror in amplifiers?
- To maintain a variable output
- To provide a voltage gain
- To produce a constant output current
Show hintHide hint
Think about its purpose in setting reference points.
4Question 4.
True or False: A common collector amplifier can improve input impedance.
- True
- False
Show hintHide hint
Consider how this amplifier interacts with loads.
Question 5.
Design a current mirror circuit for a common collector amplifier that maintains stability under varying loads. Specify the components and their values.
Show hintHide hint
Ensure to consider the saturation regions of your transistors to prevent oscillation.
Question 6.
In a differential amplifier, using the derived equations, prove that replacing passive loads with current mirrors doubles the differential gain.
Show hintHide hint
Concentrate on the multiplication of currents per mirror unit while observing the relationships.
