Abstract:
A method and apparatus for compensating for current-change induced voltage changes is disclosed. In one embodiment, a digital throttle unit coupled to an instruction pipeline may generate a compensating current signal, which may then cause a dummy load to consume a compensating current. In another embodiment, a counter responsive to changes in clock frequency may generate a ramp current signal, which may then cause a dummy load to consume a current corresponding to the ramp current signal.
