Abstract :
An improved definition of target impedance is proposed in this paper, which is derived from the time-domain waveforms of the IC transient current and the allowable voltage fluctuation. The proposed target impedance removes the unnecessary constraint in the original definition and allows for more cost-effective power distribution network (PDN) designs for consumer electronic products. A measurement procedure to obtain IC transient current waveforms is also developed for the PDN designs utilizing power traces. The proposed target impedance and the measurement procedure have been validated using practical functioning designs.
