Question 1.
Define a single-ended amplifier.
Show hintHide hint
Think about how it connects to ground.
Question 2.
What is a differential signal?
Show hintHide hint
Consider how you would derive the output from two distinct inputs.
3Question 3.
What does a single-ended amplifier amplify?
- The difference between two inputs
- One input signal with respect to ground
- Common mode signals
Show hintHide hint
Focus on the number of inputs.
4Question 4.
True or False: A differential amplifier amplifies the average of two input signals.
- True
- False
Show hintHide hint
Consider how each input interacts.
Question 5.
Given two input voltages V1 = 4V and V2 = 1V, what is the output of a differential amplifier with a gain of 3?
Show hintHide hint
Use the differential output formula.
Question 6.
If a single-ended amplifier has an input of 6V and outputs 15V, what is the gain? Then compare this with a differential amplifier when V1 is 6V and V2 is 2V; what would you expect the output to be for a gain of 2?
Show hintHide hint
Separately calculate gains and then the output based on inputs.
