Question 1

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.

Question 2

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.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
