4 cards from this section. Quick, good the night before a test.
What is the primary function of a current mirror?
Think about its use in amplifying circuits.
What does g_m represent in a current mirror circuit?
It's a measure of efficiency.
What does the small signal model of a current mirror allow us to analyze?
Think about the relationships defined in the model.
True or False: A lower common mode gain generally results in better noise rejection.
Recall the benefits of common mode rejection.
If a current mirror has g_m = 5 and the input signal is variable, derive the relationship to ascertain output in a dynamic scenario.
Dissect the relationships established in the small signal model.
Evaluate the limitations of current mirrors in practical circuits and suggest potential modifications to improve reliability.
Think about factors like output impedance and biasing.
