Abstract

See full text

The invention provides a variable gain amplifier system for use in a burst mode receiver, said system comprising an amplifier adapted to amplify a signal; a gain control module; a dc offset compensation module adapted to derive a compensation signal as a function of the amplifier gain. Compared to existing methods for dc offset compensation in variable gain amplifier, the system and method for dc offset compensation allows fast adjustment of rapidly changing dc offsets that occur in applications where the gain of the variable gain amplifier is adjusted rapidly.
