Equivalent rise time for resonance in power/ground noise estimation

— The non-monotonic behavior of power/ground noise with respect to the rise time tr is investigated for an inductive power distribution network with a decoupling capacitor. A time domain solution is provided for the rise time that produces resonant behavior, thereby maximizing the power/ground noise. The sensitivity of the ground noise to the decoupling capacitance Cd and parasitic inductance Lg is evaluated as a function of the rise time. Increasing the decoupling capacitance is shown to efficiently reduce the noise for tr ≤ 2 LgCd. Alternatively, reducing the parasitic inductance Lg is shown to be effective for tr ≥ 2 LgCd.
