5 cards from this section. Quick, good the night before a test.
Define differential mode in your own words.
Think about what happens to the output when two different signals are applied.
What does common mode refer to in a differential amplifier?
Consider what happens if the same voltage is applied to both terminals.
What does differential mode refer to in amplifier operation?
Recall how input signals affect output.
True or False: The common mode gain should preferably be equivalent to the differential gain.
Consider why we would want to ignore common signals.
Design a differential amplifier circuit that can operate within an ICMR of +1V to +5V with a supply voltage of +6V. Specify the components you would use.
Think about how resistor values can affect input voltages.
Given a differential amplifier setup that outputs a maximum voltage of +12V and a minimum of +2V, calculate the maximum output signal swing and discuss the implications of this swing on amplifier design.
Reflect on how this swing affects the load you might put on the amplifier.
