Patent ID: 6906579

Claim:
A packaged integrated circuit having a clock and an associated package inductance limiting the rate at which current supplied to a power grid of the packaged integrated circuit may change in response to a change in current demand of the packaged integrated circuit and a decoupling capacitance filtering an operating voltage, the packaged integrated circuit comprising: a regulator circuit coupled to the power grid of the packaged integrated circuit for sourcing current to the packaged integrated circuit in a first operating state and sinking current from the packaged integrated circuit in a second operating state; the first operating state corresponding to the operating voltage decreasing below a lower trigger voltage indicative of a first multicycle event that increases current demand during a first plurality of cycles of the clock of the packaged integrated circuit and the second operating state corresponding to the operating voltage increasing above an upper trigger voltage indicative of a second multicycle event that decreases current demand during a second plurality of cycles of the clock of the packaged integrated circuit; the lower trigger voltage being above a minimum safe voltage and the upper trigger voltage being below a maximum safe voltage.
