2 cards from this section. Quick, good the night before a test.
What does V_CE(sat) represent?
Think about the requirements for keeping a transistor active.
Name a benefit of having a Beta-helper circuit.
Consider how extra transistors can affect overall circuitry.
What is the minimum required voltage for a current mirror?
Consider both elements needed for active operation.
True or False: A Beta-helper circuit increases the reference current loss.
Review the impacts of adding transistors in this setting.
Design a current mirror circuit with given parameters, optimizing for the lowest minimum required voltage while ensuring current stability.
Evaluate the values of saturation and reference voltages necessary.
In a Beta-helper circuit, if β increases to 150 from 100, how does this affect the reference current and output current?
Use the relationship between current and β to analyze the situation.
