20% to 40% Switching and Dynamic Power Reduction Using the CC-100 IC, the CurrentRF PowerPad, and the CurrentRF PowerPad in Digital ICs and Systems
Electronic systems using digital circuits generate EM currents (overlap current) as an undesired byproduct of their function. This overlap current is present in all digital circuits. These current impulses are too high in frequency for Batteries and Supplies to directly provide, thus reservoir capacitors and DCAPs are utilized to supply these locally needed high frequency currents. Mounted on the ground side of reservoir capacitors and DCAPs on PCBs, the CC-100 IC intercepts this high frequency current, reprocesses and feeds back a portion of this current, and
cancels a portion of the original overlap current impulse, reducing total digital current by 10% to 40%. Maintaining the footprint of conventional IC powergrids and padring bondpads, the CurrentRF PowerGrid/PowerPad, an area reduction version of the CC-100 IC, also reduces system digital reservoir capacitor current drain by 10% to 40% of the total system battery current draw. The implementation of the CurrentRF PowerGrid/PowerPad consumes almost zero additional chip
area, and is suitable for integration into Digital/Mixed Signal/Sensor ICs, drawing no DC operational power.
