Abstract
An apparatus may include a non-linear module, a control module, and a calibration module. The non-linear module produces an output signal from an input signal. The control module selects, upon an occurrence of a calibration condition, a calibration operation from two or more calibration operations. Each of the two or more calibration operations may generate one or more correction values for the non-linear module. Further, each of the calibration operations produces the input signal from a pre-input signal. This selected calibration operation is performed by the calibration module. The two or more calibration operations include a first calibration operation and a second calibration operation. The first calibration operation produces the input signal from the pre-input signal according to a predictive technique. The second calibration operation produces the input signal from the pre-input signal according to a non-predictive technique.
