Abstract
A system and method are provided for minimizing data-dependent power variations. The system and method can include summing an input with a dither signal, processing the summed signal, and substantially removing the effects of the dither signal from the output. The output is an approximation of processing to the input alone, while certain aspects of processing activity, such as temperature changes and current draw, are less dependent on input values. Variations in data-dependent activities are thus reduced. The effects of the dither signal may be removed by equivalently processing the dither signal alone, and using that result as a compensating signal to cancel components of the processed signal that result from the presence of the dither signal.
