Characteristic Curve of Varactor DiodeCharacteristics curve of varactor diode
The graph shows the non-linear relationship between capacitance and voltage applied to diode. It is known that capacitance and width have an inverse relationship which means that as the width of the depletion region increases with the reverse voltage, the capacitance decreases (i.e. varies inversely as shown in the graph).
In short, as the reverse voltage increases, the transition capacitance falls rapidly. This behaviour can be describes as an exponential pattern.
