Abstract

Un oscilador Colpitts de tipo de cristal controlado por voltaje incluye un primer cristal y un transistor acoplado al primer cristal para proporcionar retroalimentacion positiva para generar una senal oscilatoria de salida. Una capacitancia variable se acopla al primer cristal para producir un cambio en la frecuencia de la senal osciladora cuando se produce un cambio correspondiente en la capacitancia variable. Se acopla una primera inductancia en un circuito resonante que incluye a la capacitancia variable y el primer cristal que tiene un valor que se selecciona para proporcionar un intervalo de arrastre de por lo menos 0.4% con respecto a la frecuencia de la senal osciladora. En una modalidad de la invencion se acopla un segundo cristal al primer cristal y se incluye en el circuito resonante. Se acopla una impedancia de disipacion de energia en el circuito resonante al primer cristal para disminuir una caracteristica Q del primer cristal con el fin de incrementar el intervalo de arrastre del oscilador. La primera inductancia separa al segundo cristal de cada uno del primer cristal y la impedancia de disipacion de energia para disminuir un efecto de la impedancia de disipacion de energia sobre una caracteristica Q del segundo cristal.
