Question
How the depletion width of varactor diode is releated to its capacitance?Adirectly proportionBinversely portionCequal
Solution
The capacitance of a varactor diode is inversely proportional to the depletion width. This means that as the depletion width increases, the capacitance decreases and vice versa. This relationship is due to the fact that the depletion region of a varactor diode acts as a dielectric in a capacitor. When the depletion width is large, the "separation" between the "plates" of the capacitor is large, and thus the capacitance is small. Conversely, when the depletion width is small, the capacitance is large. So, the correct answer is B: inversely proportional.
