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.
