2 cards from this section. Quick, good the night before a test.
Define the cut-in voltage for a silicon diode.
Think about when a silicon diode starts conducting significantly.
What is the reverse saturation current?
Consider the current flowing when the diode is reverse-biased.
What is the primary function of the cut-in voltage in a diode?
Recall the voltage threshold at which a diode starts to conduct.
In a circuit with V_in below V_γ, what will the output voltage be?
Think about the state of the diode when V_in is low.
Design a circuit using a diode to rectify an AC voltage source. Describe how the output voltage changes with respect to the AC input.
Think about how the diode interacts with both positive and negative peaks of AC.
You have a circuit comprising a diode and a resistor. When V_in = 5V and R = 500Ω (assuming V_γ = 0.7V), calculate the output voltage when the diode is forward-biased.
Use Ohm's law to help identify current flow through the circuit.
