2 cards from this section. Quick, good the night before a test.
What is the primary purpose of a differential amplifier?
Consider applications where noise reduction is critical.
Define common mode operation.
Think about how common signals affect the output.
What is the typical function of a differential amplifier?
Think about its role compared to a standard amplifier.
In common mode operation, should the gain ideally be high or low?
Consider the ideal scenario for differentiated signals.
Analyze a differential amplifier circuit configured with two BJTs, calculating the input common mode range and the expected differential voltage gain given specific resistor values.
Utilize small signal analysis techniques covered in class for detailed steps.
Given an array of signals input to a differential amplifier, determine how the output responds in terms of gain and stability when varying the common mode signal levels.
Focus on the idea that varying the inputs changes how the circuit handles the common signals.
