Question 1.
What is the primary function of a differential amplifier?
Show hintHide hint
Think about what happens when two signals are fed into it.
Question 2.
Define common mode signal.
Show hintHide hint
It's the unwanted noise that the amplifier targets to suppress.
3Question 3.
What is the main purpose of a differential amplifier?
- To amplify only common mode signals
- To amplify the difference between two input signals
- To output only single-ended signals
Show hintHide hint
Think about the amplifier's primary function!
4Question 4.
True or False: Differential amplifiers only work with perfectly matched input signals.
- True
- False
Show hintHide hint
Consider the design of differential amplifiers.
Question 5.
Given two input signals with a known differential voltage, calculate the expected output of a differential amplifier if its gain is known.
Show hintHide hint
Set up the formula before plugging in the numbers.
Question 6.
Design a simple circuit using a differential amplifier and suggest how to minimize noise in this circuit.
Show hintHide hint
Consider how components are arranged and the environment in which they are used.
