Challenge Problems
Push your limits with advanced challenges
Consider a diode circuit subjected to a varying input voltage that fluctuates between 0.5V and 1V. Analyze how the output voltage behavior will compare with a circuit where the input remains constant at 0.8V.
💡 Hint: Think about how variation affects the average output.
Using the piecewise linear model, derive an expression for the output voltage as a function of input voltage for a diode operating above its cutting voltage with a resistance in series.
💡 Hint: Factor in both the voltage drops across the diode and the series resistance.
