Question 1.
What is a differential amplifier?
Show hintHide hint
Think about the purpose of amplification.
Question 2.
Define common mode gain.
Show hintHide hint
Consider signals that do not vary.
3Question 3.
What is the primary purpose of a differential amplifier?
- To amplify a single input signal
- To amplify the difference between two signals
- To reduce noise in a noisy environment
Show hintHide hint
Remember the definition of differential amplification.
4Question 4.
True or False: A higher CMRR indicates better rejection of common mode signals.
- True
- False
Show hintHide hint
Think about the implications of increasing CMRR.
Question 5.
Design a differential amplifier circuit using both BJT and MOSFET. What changes would you expect in the performance metrics?
Show hintHide hint
Focus on the characteristics of both types of transistors.
Question 6.
Given a theoretical differential amplifier with a differential mode gain of 150 and a common mode gain of 8, calculate the CMRR in dB.
Show hintHide hint
Remember to apply the logarithm for converting ratios into decibels.
