2 cards from this section. Quick, good the night before a test.
What is the primary function of a current mirror?
Think about what current mirrors are typically used for.
What two types of transistors are commonly used in current mirrors?
Recall the types of transistors mentioned in class.
What is the purpose of a current mirror?
Think about its basic application in circuits.
True or False: The output current of a current mirror is independent of output voltage.
Consider the effects of voltage on current.
Design a current mirror circuit using a MOSFET to replicate a 10 mA reference current. Calculate expected output current if the aspect ratio is 3:1.
Use the aspect ratio formula for output current.
Explain how you would modify a current mirror to improve its output resistance. Detail the components and configuration changes needed.
Consider how additional transistors might help stabilize the voltage.
