Show hintHide hint
Think about what happens when you apply the same signal to both inputs.
Question 2.
What does DC operating point ensure?
Show hintHide hint
Consider the relationship between voltage and transistor operation.
3Question 3.
What is the primary function of a differential amplifier?
- To amplify a single input
- To amplify the difference between two inputs
- To eliminate noise
Show hintHide hint
Think about the inherent design of differential amplifiers.
4Question 4.
True or False: The common mode gain is always positive.
- True
- False
Show hintHide hint
Consider the definition of common mode gain.
Question 5.
Calculate the effective common mode gain when you have a common mode voltage of 1V resulting in 3V at the output. If a differential voltage of 2V is applied, what will be the output voltage?
Show hintHide hint
Remember to break down the problem step by step.
Question 6.
Design a differential amplifier circuit with specific resistor values that allows for a maximum input common mode voltage of 5V, where both transistors stay in their active region.
Show hintHide hint
Focus on the specifications provided and balance both active regions.
