The reverse voltage applied to a varactor diode
is less than avalanche breakdown voltage
is more than avalanche breakdown voltage
may be more or less than a avalanche breakdown voltage
is very high as compared to avalanche breakdown voltage
Correct Answer:
is less than avalanche breakdown voltage
Explanation:
The action of varactor diode is due to the capacitance of depletion layer. The thickness of depletion layer depends on the reverse bias which should not cause breakdown.
