Abstract

Se describen los sistemas y métodos para reducir la interferencia entre los osciladores controlados de los bucles de enganche de fase (PLLs). En una forma de realización, un sistema incluye un primer PLL que incluye un primer oscilador controlado y un segundo PLL. El sistema de la reivindicación además incluye un generador de señal de compensación adaptado para generar una señal de compensación en una frecuencia de desplazamiento que es aproximadamente igual a un desplazamiento entre las frecuencias de salida de las primeras y segundas PLL y aplicar la señal de compensación al primer oscilador controlado de modo que la señal de salida del primer oscilador controlado se modula con la señal de compensación. Una amplitud y una fase de la señal de compensación son de modo que, cuando la señal de compensación se aplica al primer oscilador controlado, se reduce una señal de interferencia producida por el primer oscilador controlado resultante de la interferencia del segundo oscilador controlado del segundo PLL al primer oscilador controlado del primer PLL.
