Subject field(s)
  • Printed Circuits and Microelectronics
DEF

A two-terminal solid-state device that utilizes the voltage-variable capacitance of a pn junction.

OBS

In the normal semiconductor diode efforts are made to minimize inherent capacitance while in the varactor, this capacitance is emphasized. Since the capacitance varies with the applied voltage, it is possible to amplify, multiply, and switch with this device.

CONT

La capacité de transition, susceptance parasite dans les jonctions PN courantes, est utilisée dans certaines jonctions comme élément réactif variable. Ces jonctions, appelées varactors ou encore diodes à capacité variable, travaillent normalement dans leur zone de polarisation inverse et présentent une capacité variable avec la tension inverse appliquée.
