Question 1
What is the primary purpose of a differential amplifier?
- To amplify a single input signal
- To amplify the difference between two input signals
- To measure current flow
💡 Hint: Think about what makes it different from a regular amplifier.
Question 2
True or False: A higher CMRR indicates better performance for rejecting common-mode signals.
- True
- False
💡 Hint: Consider the direct relationship between CMRR and noise rejection.

Question 1
For a differential amplifier configured with transistors having a total collector current of 2mA and resistances of 10kΩ at the collectors, if Vid = 500mV, calculate Ad.
💡 Hint: Keep in mind that Ad will be negative due to the phase shift.
Question 2
If a differential amplifier has an Acm of 1V and Ad of 25, what is the CMRR in dB?
💡 Hint: Remember to convert to decibels following the formula provided.
