摘要:
A resonance suppression circuit is provided to suppress resonance on a power grid of a chip or die. The resonance suppression circuit may include a band-pass filter portion, a comparator portion, an amplification portion and a current dissipation portion. The band-pass filter portion may include an inverter coupled between two signal lines of the power grid. The comparator portion may sense voltage fluctuations at approximately the resonance frequency and trigger the current dissipation portion to turn ON and thereby change the frequency spectrum of the load current on the power grid to suppress the power grid resonance.
