3 cards from this section. Quick, good the night before a test.
Define output resistance in the context of amplifiers.
Think about the relationship between current and voltage.
What do we mean by small signal model?
Recall how we simplify the circuit for small AC signals.
What does output resistance indicate in an amplifier?
Think about what happens when loads change connected to the amplifier.
True or False: High output resistance is always ideal for amplifier design.
Reflect on the relationship between output resistance and load interaction.
A Common Source Amplifier has an output voltage of 12V when the load current is 3mA. Calculate the output resistance.
Remember to convert mA to A when performing calculations.
If a voltage gain of an amplifier is -10 and the transconductance is 2 mA/V, what is the output resistance?
Make sure to maintain focus on the signs in your calculations!
