An integrated circuit for saturation detection comprises: a plurality of gain components; a plurality of saturation detectors with each saturation detector operably coupled to an output of one of the gain components; a plurality of logic elements with a first input of each logic element associated with an output of one of the saturation detectors; and a controller operably coupled to the plurality of logic elements. The controller is arranged to apply a signal to a second input of individual ones of the plurality of logic elements such that an output of the respective logic element identifies a saturation event of the saturation detector associated with that respective logic element.
