Question 1.
What does the common mode gain signify?
Show hintHide hint
Consider signals that are identical on both inputs.
Question 2.
Define what a current mirror does.
Show hintHide hint
Think of it like a mirror reflecting the same current.
3Question 3.
What is the primary function of a current mirror?
- To amplify voltage
- To provide a constant output current
- To reduce noise
Show hintHide hint
Reflect on how mirrors function in general.
4Question 4.
True or False: Common mode gain should ideally be much higher than differential mode gain.
- True
- False
Show hintHide hint
Consider the definitions we discussed.
Question 5.
Design a common source amplifier circuit that uses a current mirror for load. Explain how changes in the load affect common mode gain.
Show hintHide hint
Think about the principle of current flow and stability with different loads.
Question 6.
Analyze how reducing the common mode gain impacts the signal clarity in a noisy environment.
Show hintHide hint
Use real-world examples of communication systems to illustrate.
