Abstract
A predistorter for reducing spurious emissions in an amplified signal including a first path configured to generated memory-less distortion correction and one or more second paths configured to generate memory distortion correction. The paths contain one or more dynamically controllable delay circuits that are configured such that the memory-less and memory distortion correction remains independent irrespective of frequency of use of the predistorter.
