Abstract

En una modalidad, una fuente de bajo ruido incluye: una fuente de señal; un amplificador variable adaptado para amplificar una señal de salida proveniente de la fuente de señal para proporcionar una señal amplificada; un amplificador de alimentación de reenvío adaptado para amplificar la señal amplificada a fin de proporcionar una señal de salida amplificada; un sistema de medición de ruido de fase adaptado para proporcionar una primera señal de retroalimentación en respuesta al ruido de fase en la señal de salida amplificada; y un procesador adaptado para controlar la amplificación suministrada por el amplificador variable en respuesta a la señal de retroalimentación a fin de reducir al mínimo el ruido de fase en la señal de salida amplificada.
