What is a varactor diode? Explain in about 150 words.
Answers
Answer:
Varactor diode is a p-n junction diode whose capacitance is varied by varying the reverse voltage. Before going to varactor diode, let’s first take a look at the capacitor.
Answer:
♀Hey mate!!
Here is ur answer ♂
Explanation:
Varactor diode is a one kind of semiconductor microwave solid-state device and the applications of this diode mainly involve in where variable capacitance is preferred which can be accomplished by controlling voltage. These diodes are also named as varicap diodes. Even though the outcome of the variable capacitance can be showed by the normal P-N junction diodes, but these diodes are chosen for giving the desired capacitance changes as they are special types of diodes. Varactor diodes are specifically fabricated and optimized such that they permits a high range of changes in capacitance.
