Challenge Problems
Push your limits with challenges.
Question 1
In a circuit with a silicon diode, calculate the output voltage when the input voltage is 1.5V given that the cut-in voltage is 0.7V and the series resistor is 1kΩ.
💡 Hint: Don't forget to consider the on-resistance and how it affects the voltage drop.
Question 2
Design a diode clipping circuit using a 1N4148 diode that clips the negative portion of an input sine wave of amplitude 1V. Determine the conditions for successful operation.
💡 Hint: Ensure your DC bias accounts for the clipping behavior above the cut-in voltage.
