2 cards from this section. Quick, good the night before a test.
What is the purpose of a current mirror?
Think about circuit stability.
Define output impedance in the context of current mirrors.
What happens if you have low impedance?
What primary role does a current mirror serve in a circuit?
Think about circuits where current consistency is key.
True or False: The output impedance can be low in effective current mirrors.
What happens to circuit current if impedance is low?
Design a simple current mirror using BJTs and analyze its output characteristics. Specify how you would measure the output impedance.
Think about the conditions under which BJTs operate well.
Explain how temperature variation might affect the performance of a current mirror. What steps could be taken to minimize this effect?
Consider how components react to changing temperatures in circuits.
