. Varactor Diode is short for variable capacitance diode Also called Tuning Diode or Varicap Diode Used Kmktvat variable capacitive diodes Depending on the effort against them. And bilateral Sa'wi is essentially a link Bi-connected in the opposite direction so as In Figure
Theory of operation:
When the voltage increases, the reverse feeding area Depletion expands, thereby increasing the thickness of the insulation And When connecting link bilateral capacitive inversely , form what is called the depletion region Region are working instead of insulating the intensive The region P, N and the region they are working Klouhy intense. lacking capacity, and when effort is decreasing nutrition Reverse narrowing the thickness of depletion region and thus Increase capacity.
