3 cards from this section. Quick, good the night before a test.
What is the main function of a diode?
Think about how water flows through a one-way valve.
What happens when the voltage applied to a diode is below the cut-in voltage?
Consider the diode as a gate that only opens at a certain voltage.
What is the behavior of a diode when the voltage is below the cut-in voltage?
Recall the condition for current flow.
In a diode's I-V characteristic, what happens in the ON region when the input voltage exceeds cut-in voltage?
Focus on the exponential nature of the I-V relationship.
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.
Deduct the resistor's influence after identifying the diode's conducting state.
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?
Consider the maximum AC signal’s peak to keep the overall characteristics linear.
