A pn junction diode that acts as a voltage variable capacitor under reverse bias condition is known as varactor diode. Varactor diode is a pn junction diode that is especially operated in reverse biased mode. It is a device whose capacitance varies with the variation in the applied reverse bias.
In certain applications and specific types of diodes (e.g., light emitting diodes (leds), zener diodes, or varactor diodes), the diode requires an external power source and.
It is used as a variable capacitor whose capacitance is controlled by adjusting the applied. Varactor diodes are mostly operated under reverse bias conditions; The cross section of a varactor diode shows the. While standard diodes are used for current conduction, varactor diodes are specialized for their capacitance characteristics and are primarily operated in reverse bias to.
Here, active and passive components integrated on a special substrate will supply the crucial contribution for future miniaturization. Therefore, there is no conduction.
