2 cards from this section. Quick, good the night before a test.
What is a current mirror?
Think about how it regulates current.
How do you define common mode gain?
Common mode means applying the same signal.
What does a current mirror achieve in a differential amplifier?
Consider its role in regulating current flow.
True or False: Differential mode gain is when the same signal is applied to both inputs.
Think about the definition of differential input.
Design a current mirror circuit using BJTs to maintain a tail current of 1mA. Specify component values needed.
Draw the circuit diagram and calculate the necessary parameters.
Determine the common mode and differential mode gain of a given differential amplifier circuit with the current mirror configuration.
Relate your findings back to the concept of gain in amplifiers.
