Abstract

Power integrity is a serious issue in the modern CMOS digital systems, because power supply noise excited in core circuits induces logic instability and electromagnetic radiation. Therefore, chip-package co-design is becoming important by taking into consideration the total impedance of power distribution network (PDN) seen from the chip. Especially, parallel resonance peaks in the PDN due to the chip-package interaction induces the unwanted power supply fluctuation, and results in the degradation of signal integrity and electromagnetic interference (EMI). In this paper, effects of critical damping condition for the total PDN impedance on power supply noise has been studied by adding different RC circuit to the intrinsic on-die RC circuit of chip. Three test chips were assumed to be designed with different on-chip PDN properties. The measurement and analysis of power supply noises for the three test chips showed typical characteristics of oscillatory region and damped regions The critical damping condition against the anti-resonance peak has been proved to be effective to suppress the power supply noise on the chip.
