2 cards from this section. Quick, good the night before a test.
What is the function of a current mirror in a circuit?
Think about how currents can be mirrored in circuits.
If you have a load resistor of 10 k ohms and a current of 2 mA, what is the voltage drop across the resistor?
Use Ohm's law for voltage calculations.
What does the term 'current mirror' refer to in electronics?
Think about the concept of copying a current in circuits.
True or False: A differential amplifier amplifies the same signal applied to both inputs.
Recall the purpose of a differential amplifier!
For a given circuit with two resistors in parallel of values 100 kΩ and 150 kΩ connected to a current mirror output, calculate the effective resistance seen by the current mirror. Discuss how this can impact the overall circuit performance.
Think about how parallel resistances work.
In a differential amplifier with one transistor having a significantly high beta than the other, devise a method to analyze how current imbalances may affect the output. Provide a solution outlining your approach to troubleshooting.
Reflect on how biasing impacts current flow.
