Abstract
Systems and methods are disclosed for providing automatic gain control of a multi-stage system. A method can include defining at least one parameter that is adapted to at least one of maximize hardware capacity of each of a plurality of gain stages and mitigate part-to-part variations of the multi-stage system. An order is selected for training the plurality of stages based on relative noise dominance for the plurality of stage. For a given stage of the plurality of stages, which is selected according to the selected order, output signals of the multi-stage system are measured over a plurality of gain settings for the given stage. A gain setting of the given stage of the multi-stage system also is configured based on the measured output signals relative to the at least one parameter defined for the given stage. The plurality of gain stages can include an analog equalizer as well programmable gain amplifiers connected in series.
