Varactor Diode

Varactor diodes, also known as variable capacitance diodes or tuning diodes, are semiconductor devices that exhibit a voltage-dependent capacitance. This unique property makes them invaluable in a wide range of electronic circuits, particularly in applications that require precise frequency control, tuning, and signal processing. Understanding Varactor Diodes Varactor diodes are essentially reverse-biased p-n junction diodes, … Read more

The capacitance of a varactor diode, also known as a voltage-variable capacitor (VVC), can be precisely controlled by adjusting the reverse bias voltage applied to the device. This ability to dynamically change the capacitance makes varactor diodes an essential component in various electronic circuits, including tunable filters, voltage-controlled oscillators (VCOs), and phase-locked loops (PLLs).
