Question 1.
Define differential gain.
Show hintHide hint
Think about how amplifiers respond to differences between input voltages.
Question 2.
What does a current mirror do?
Show hintHide hint
Consider its purpose in biasing transistors.
3Question 3.
What is differential gain?
- A. Gain from common mode signal
- B. Gain from input voltage difference
- C. Gain from output to input reconnection
Show hintHide hint
Focus on the terms 'differential' and 'gain', tied to input differences.
4Question 4.
The purpose of a current mirror is to:
- True
- False
Show hintHide hint
Think about how effective they are in maintaining current consistency.
Question 5.
You have a differential amplifier with a differential input of 0.1 V and common mode input of 1 V. If the differential gain is 2000, what will be the output voltage?
Show hintHide hint
Focus on how the differential gain is applied to the input difference.
Question 6.
Calculate the impact of Early voltage on the output current of a current mirror if the Early voltage is 50V and Vce for the output transistor is 1V.
Show hintHide hint
Think about how the current mirror effectiveness correlates with Early voltage.
