Diodes and Applications

Q1: A diode for which you can change the reverse bias, and thus vary the capacitance is called a

A varactor diode

B tunnel diode

C zener diode

D switching diode

ANS:A - varactor diode

A varacter diode is basically a reverse biased PN junction which utilises the inherent capacitence of the depletion layer. It is also known as varicap, voltcapor tunning diode. It is used as a voltage variable capacitor.
