METHOD AND APPARATUS FOR SMOOTHING CURRENT CONSUMPTION IN AN INTEGRATED CIRCUIT

摘要

The invention includes a system for smoothing current consumption in a digital logic module. A processing circuit is configured to receive an input and manipulate the input during a processing time period to produce an output. A non-processing time period follows production of the output. The processing circuit is further configured to draw an active range of current during the processing time period and an inactive range of current during the non-processing time period. The system comprises a smoothing circuit coupled to the processing circuit and configured to engage the processing circuit during the non-processing time period. The smoothing circuit is also configured to cause the processing circuit to draw an active range of current during the non-processing time period.
