4 cards from this section. Quick, good the night before a test.
What is common-mode voltage?
Think of it as the center level around which both signals oscillate.
Define differential mode gain.
It's how effectively the amplifier can amplify differences.
What is the threshold voltage for MOSFETs?
Recall the specification of MOSFET operations.
True or False: A common-mode voltage that is too low can prevent a transistor from working effectively.
Think about how voltage polarity affects operation.
Design a differential amplifier with specified parameters and calculate the appropriate common-mode voltage range ensuring it's correctly set within operational limits.
Use known threshold voltages and resistance values in calculations.
If the differential gain is 50 and common-mode gain is -1, what adjustments can be made to improve gain response without compromising performance? Provide a concise modification plan.
Consider how active components interact in comparison to passive components.
