Abstract

Una pluralidad de amplificadores se encuentran conectados en cascada para formar un circuito de pre-distorsion en línea. Los amplificadores no estánbalanceados por cuanto cada etapa del amplificador en el circuito tiene dos vallas de tension continuaque se controlan de modo independiente, para proveerdiferentes niveles de tension continua -es decir, desviados- a los amplificadores no balanceados. Este desbalanceo en los amplificadores genera lapre-distorsion en una senal que puede emplearse para cancelar la distorsion inherente causada por un dispositivo no lineal, que posteriormente procesa otransmite la senal pre-distorsionada. El control de la tension de desnivel continua por lo menos en una de las etapas del amplificador es necesario paraigualar la pre-distorsion con la distorsion inherente que se está corrigiendo. Un circuito de inclinacion puede emplearse en cascada con la pluralidad deamplificadores (frente a los amplificadores de RF) para compensar el cambio de amplitud causado por los amplificadores de RF no balanceados. Es posible cambiarcualquier lado de la tension continua a los efectos de corregir toda la curva del diodo, tanto sublineal o superlineal.
