ABSTRACT:
An apparatus and method for performing adaptive power regulation for an integrated circuit. The present invention utilizes a voltage regulator circuit (16) to regulate the voltage provided to an integrated circuit core (12), and to thereby reduce the power consumption of the integrated circuit core (12). In one form, the voltage regulator circuit (16) utilizes two voltage converting mechanisms, namely an inductive converter (22) and a resistive converter (24). The inductive converter (22) and the resistive converter (24) supplement each other in order to supply the current required by integrated circuit core (12). All or a portion of voltage regulator (16) may be located on the same integrated circuit substrate as integrated circuit core (12).
