Abstract

Det er vist en forsterker (102) som kan forspennes dynamisk. En kontroller (118) avgjør når forspenningen til forsterkeren (102) skal endres, for å oppnå lav frekvenssplatter. Dette oppnås ved å endre forspenningsnivået på forsterkeren (102) mellom en vesentlig lineær (klasse A) driftsmodus, og en vesentlig ikke-lineær (klasse B) driftsmodus. Under de kritiske perioder der forsterkeren (102) slås på og av, blir forsterkeren (102) plassert vesentlig i lineær driftsmodus, for dermed å redusere utgangsharmoniske som utvikler seg. I et annet aspekt ved oppfinnelsen er vist en radio (300) som anvender en dynamisk forspent forsterker (102).An amplifier (102) is shown which can be biased dynamically. A controller (118) determines when to change the bias of the amplifier (102) to obtain low frequency plates. This is achieved by changing the bias level of the amplifier (102) between a substantially linear (class A) operating mode and a substantially non-linear (class B) operating mode. During the critical periods when the amplifier (102) is turned on and off, the amplifier (102) is placed substantially in linear operating mode, thus reducing output harmonics which develop. In another aspect of the invention there is shown a radio (300) using a dynamic biased amplifier (102).
