Abstract
The invention proposes an integrated circuit arrangement () for generating a digital variable gain control signal (SA) for a digitally variable gain amplifier (), comprising: a memory () for storing at least one digital signal sequence (DS) defining a time gain profile, a controller () for generating the digital variable gain control signal (SA) by reading out the memory (), and a programming interface () for programming the memory (). The integrated circuit arrangement () in accordance with the invention makes it possible to read out e.g. a gain characteristic as needed at the time for an ultrasound or radar application of a VGA in fast response at a defined rate from the memory ().
