In electronics, a varicap diode, varactor diode, variable capacitance diode, variable reactance diode or tuning diode is a type of diode designed to exploit the voltage-dependent capacitance of a reverse-biased p–n junction.
26 cze 2024 · Dioda Varicap, znana również jako dioda waraktorowa lub dioda o zmiennej pojemności, jest urządzeniem półprzewodnikowym, które wykazuje zmienną pojemność przy polaryzacji zaporowej.
12 sty 2024 · A varactor diode, also known as a Varicap or volt-cap, is a type of PN junction diode primarily utilized in the reverse-biased mode. It is a device whose capacitance varies with the variation in the applied reverse bias potential.
Learn about the capacitance characteristics and applications of varicap diodes, which use the depletion layer in reverse-biased pn junctions. Download the PDF chapter of basic knowledge of discrete semiconductor devices.
15 sty 2020 · In this tutorial, we discussed about the varicap diode, and what characteristics of the diode were optimized to develop it. We also discussed how a diode resembles a capacitor, and how it acts as a variable capacitor as the amount of the reverse bias applied to it is changed.
A varactor is a diode whose junction capacitance can be altered with an applied reverse voltage. For this reason, a varactor is also called a variable capacitance diode (also it's called a varicap). A varactor's capacitance varies as the applied reverse voltage to it changes.
25 mar 2024 · A varactor diode is a p-n junction diode that acts as a variable capacitor under reverse bias voltage. Learn how it works, its characteristics, equivalent circuit and applications in this comprehensive guide.
