Abstract:
1. An integrated circuit comprising: a plurality of resonance limiter circuits coupled to a power supply connection of the integrated circuit, wherein the plurality of resonance limiter circuits are configured to detect oscillation on the power supply connection for at least a resonant frequency and to dampen the resonant frequency oscillation responsive to detecting the oscillation, wherein the resonant frequency depends on electrical characteristics of a package of the integrated circuit, wherein the package protects the integrated circuit and provides for electrical connection of the integrated circuit to other components, and wherein the plurality of resonance limiter circuits comprise two or more groups of resonance limiter circuits; and an enable unit coupled to the plurality of resonance limiter circuits, wherein the enable unit is configured to provide logically separate enables to each group, whereby the groups are separately enableable.
