Abstract
En este artículo se presenta la integración de un amplificador de envolvente de una etapa con un amplificador de clase E mediante la técnica de Kahn o Eliminación y restauración de envolvente (EER). Esta técnica se basa en la combinación de un amplificador de potencia conmutado de alto rendimiento alimentado por una fuente de alimentación modulada. El amplificador de envolvente se ha implementado con un convertidor reductor síncrono con red de cancelación de rizado, lo cual permite reducir la relación entre la frecuencia de conmutación y el ancho de banda de gran señal del amplificador de envolvente, que es uno de los factores de diseño más limitantes en esta ap...
