4 cards from this section. Quick, good the night before a test.
Define a current mirror.
Think about its primary function in electronic circuits.
What is base current loss?
It impacts the output current.
What is the primary function of a current mirror?
Focus on the core utility of current mirrors in circuits.
True or False: A cascode transistor decreases the output resistance of a current mirror.
Think about its role in improving stability.
Design a current mirror using BJTs to output a current of 2mA with an acceptable Vbe drop of 0.7V; calculate Rbias.
Use Ohm's law as a foundation for calculations.
If a MOSFET current mirror must mirror a 3mA current with Vth = 1V at 10V supply, what should the aspect ratio be?
Consider how Vgs influences the Id for your calculations.
