What is a vaactor diode?
The vaactor diode, more often referred to as Varikap, is an electronic semiconductor device very closely related to the standard diode, but with certain capacitor capabilities. The difference between VaroN and the standard diode is that the standard diode is designed to minimize the capacity of the device, while the varoque diode is designed to use and use capacity. Varactor diodes find common use in parametric electronics, such as parametric amplifiers and other tuning circuits that can be changed by changing the voltage. One material is negatively charged, called cathode, and the other is positive, called anode. When the diode is first created, these two materials exchange electrons where they meet and create an area in a diode called a depletion layer that does not have a preference. Creating two different diode fees is done by adding negative or positive material to the diode matrix. In a normal diode, this charged material is added as nMore ejmodernly, the cathode and anode width to allow the diode to change the states as quickly as possible and at the lowest possible voltage level.
If negative voltage is applied to the anode conductor, the potential of the negative voltage combines with the potential of negative cathody. Once this force is strong enough to bridge a layer of exhaustion, it will easily move on a positively charged diode anode and the diode will perform electricity. In this state, the diode is reported to have forward distortion.
When the same voltage is applied to the cathode lead in the diode, the depletion layer expands on both sides of the anode, with a positive anode with sandwiches between two negative forces to create the capacity of the electric field inside the diode. Initially, this field slows down the flow of the electric current passing through the diode, but as the voltage increases and the field is built in the strength, the field is eventually strong enough to block the electric current from completehim to pass through the diode. The diode in this state is reported to have reverse distortion.
Most diodes are designed to pass as quickly as possible in the area as the current still flows and there is a capacity electric field. However, the Varaktor LED is designed to work in this zone. Unlike the standard diode, the charged material in the variator is added to the gradient pattern that changes the power of the charge over the width of the cathode and the anode. The depletion layer of the diode designed in this way varies in width in relation to the voltage applied to it. As a result, the diode can act as a variable capacitor with a capacity field, decrease, as more voltage applies and increases and increases as less voltage is applied.
Vactor diode can be used instead of more expensive and more difficult installation of the device, such as a variable capacitor. However, the varactor diodes are always not only used to reduce costs and alleviate production processes. Varaktors are often used in applications such as television or break upSand tuners where their skills allow them to lock very quickly at the frequency of channel or stations.
