    Flashcard drill

    3 cards from this lesson. Good the night before a test.

Try these first

  1. 1.

    What is the main function of a diode?

    Hint

    Think about how water flows through a one-way valve.

  2. 2.

    What happens when the voltage applied to a diode is below the cut-in voltage?

    Hint

    Consider the diode as a gate that only opens at a certain voltage.

  3. 3.

    What is the behavior of a diode when the voltage is below the cut-in voltage?

    • True
    • False
    Hint

    Recall the condition for current flow.

  4. 4.

    In a diode's I-V characteristic, what happens in the ON region when the input voltage exceeds cut-in voltage?

    • The current remains zero
    • The current exponentially increases
    • The current decreases
    Hint

    Focus on the exponential nature of the I-V relationship.

  5. 5.

    Given a diode with an I-V characteristic reaching 1V, calculate the expected output voltage if the input is 3V and the voltage drop across a resistor is 1V when the diode is ON.

    Hint

    Deduct the resistor's influence after identifying the diode's conducting state.

  6. 6.

    Design a circuit with a diode and a resistor enough to establish a working AC signal overlaid on a DC bias of 2V. What considerations do you have for the cut-in voltage?

    Hint

    Consider the maximum AC signal’s peak to keep the overall characteristics linear.
