Un diodo varactor es un componente clave dentro de un VCO. La base de funcionamiento del diodo varactor es bastante simple. En cada extremo del diodo son las regiones P y N donde la corriente puede ser conducida. Esto tiene el efecto de cambiar la distancia entre las placas del condensador. Algunos diodos varactor pueden ser referidos a tipos tan abruptos y hiper abrupto.

Esto da diferencias significativas en el rendimiento de los dos tipos de diodo varactor. Esto proporciona una cuarta dependencia de la frecuencia la ley inversa.

Algunos incluso pueden operar hasta tanto como 60 voltios, aunque en el extremo superior de la gama es visto relativamente poco cambio en la capacitancia. Al asegurarse de que hay suficiente margen, el circuito es menos probable que falle. Para osciladores utilizados en los sintetizadores de frecuencia afecta al rendimiento del ruido.

Diodos High Q permiten un circuito sintonizado Q superior a alcanzar, ya su vez, esto reduce el ruido de fase producida por el circuito. Para los filtros de la Q es de nuevo muy importante. Diodo varactor circuito equivalente El Q depende de la resistencia en serie que las exhibiciones diodo varactor.

El otro extremo puede entonces tener el potencial sesgo aplicado. Sin embargo, pueden introducir inductancia espuria y bajo algunas circunstancias pueden causar oscilaciones espurias que se produzca cuando se utiliza en un oscilador. Un valor de 10 kohms es a menudo un buen punto de partida.

Translation of "varactor" in Spanish

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. Varactors are used as voltage-controlled capacitors. They are commonly used in voltage-controlled oscillators , parametric amplifiers , and frequency multipliers. Phase-locked loops are used for the frequency synthesizers that tune many radios, television sets , and cellular telephones. The varicap was developed by the Pacific Semiconductor subsidiary of the Ramo Wooldridge Corporation who received a patent for the device in June
