Abstract

Un circuito de ajuste monolítico de oscilador controlado por tension de alta frecuencia incluye varios lazos de capacitancia conectadosselectivamente entre una primera y una segunda entrada diferencial de una red activa de oscilador de tension. Varios diodos, conectados en serie conotros tantos lazos de capacitancia, conectan selectivamente lazos de capacitancia correspondientes entre la primera y la segunda entrada diferencial cuandotienen bias positivo. Del mismo modo, los varios diodos desconectan selectivamente los lazos de capacitancia correspondientes de la primera y segundaentrada cuando el bias es inverso. Un controlador aplica una tension de bias positivo al diodo del lazo de capacitancia seleccionado para conectar ellazo de capacitancia a la red activa del oscilador controlado por tension y aplica una tension de bias inverso al diodo del lazo de capacitancia seleccionadopara desconectar el lazo de capacitancia de la red activa.
