Question 1.
What does a differential amplifier do?
Show hintHide hint
Think about how it processes inputs.
Question 2.
What is the role of the emitter node?
Show hintHide hint
Consider how it relates to output signals.
3Question 3.
What is the primary function of a differential amplifier?
- To amplify the sum of the inputs
- To amplify the difference between inputs
- To output the maximum input voltage
Show hintHide hint
Remember the name 'differential' refers to the difference.
4Question 4.
In which configuration does the output voltage follow the input voltage closely?
- Common Emitter
- Common Collector
- Common Base
Show hintHide hint
Think about the phase relationship between input and output.
Question 5.
Design a differential amplifier circuit that would best enhance the gain by using active components. Justify your choices.
Show hintHide hint
Consider how feedback might stabilize the system while providing high gain.
Question 6.
Given a common emitter circuit with specified values for R, determine the output voltage if the input changes by a specific amount.
Show hintHide hint
Look closely at how the input affects the output considering the circuit's parameters.
