发明名称 Resonance limiter circuits for an integrated circuit
摘要 In one embodiment, an integrated circuit comprises resonance limiter circuits coupled to a power supply connection of the integrated circuit. The resonance limiter circuits are configured to detect oscillation on the power supply connection at a resonant frequency, and to dampen the resonant frequency oscillation responsive to detecting the oscillation. In some embodiments, the resonance limiter circuits may damp oscillation at or above the resonant frequency or approximately the resonant frequency (e.g. somewhat below the resonance frequency). The resonant frequency depends on a package of the integrated circuit. In an embodiment, a resonance limiter circuit comprises a filter and a transistor coupled in parallel with the filter between a power supply connection and a ground connection. The filter is tuned to approximately a resonant frequency (e.g. the lowest resonant frequency) that depends on a package corresponding to an integrated circuit into which the resonance limiter circuit is fabricated.
