A CPU core-power interconnect design was pre- viously proposed for reducing radiated emissions that result from current injected into a motherboard. The EMI-suppressing design increases the inductance to the motherboard to filter the harmonics of the processor. The change in inductance and resistance, however, may prove detrimental to the core power integrity. Higher inductance will shift the chip-package resonance, possibly rendering the package capacitors useless. A significant resistance… CONTINUE READING
