Abstract
An adjustable gain control (AGC) system with improved gain control accuracy and method thereof is disclosed. The system includes an offset circuit for providing an offset signal that is selectable; a gain setting source for providing a gain set signal that is dependent on a desired gain and the offset signal; and an AGC circuit, coupled to the offset signal and gain set signal, for providing a gain control signal, the AGC circuit compensating, according to the offset signal, the gain control signal for process variables corresponding to the AGC circuit to provide a plurality of predetermined gains for the amplifier that correspond, respectively, to a plurality of desired gains indicated by respective gain select signals.
