Abstract
An electronic circuit, such as a transmitter, for receiving a modulating signal including an in-phase component (I) and a quadrature component (Q). The electronic circuit has a first digital-to-RF-amplitude convertor (DRAC) receiving the in-phase component and a second digital-to-RF-amplitude convertor (DRAC) receiving the quadrature component. The first digital-to-RF-amplitude convertor is operative in a first duty cycle that is different from 50% and the second digital-to-RF-amplitude convertor is operative in a second duty cycle that is different from 50% and substantially the same in value as said first duty cycle.
