4 cards from this section. Quick, good the night before a test.
What is the primary purpose of a current mirror?
Think about the functions it serves in circuits.
Define small signal analysis.
Recall how we treat DC and AC components separately.
What is the main function of a current mirror?
Consider its role in circuit design.
True or False: A small signal model only applies to circuits operating without a DC bias.
Think about DC conditions in circuit operation.
Design a current mirror circuit using a BJT and calculate the output current for a given input current under small signal conditions. Explain your methodology.
Remember the concept of matching currents and how to apply transconductance.
Evaluate the impact of temperature variations on the stability of a current mirror circuit and suggest design improvements.
Consider factors that could cause current shifts in semiconductor devices.
