TL;DR: In this paper, a physics-based dipole moment source reconstruction was proposed to estimate the near-field coupling between a liquid crystal display panel to a cellphone's cellular antenna, based on the understanding of the current distribution on the source.

TL;DR: In this article, an improved definition of target impedance is proposed, which is derived from the time-domain waveforms of the IC transient current and the allowable voltage fluctuation, which allows for more cost-effective power distribution network (PDN) designs for consumer electronic products.

TL;DR: In this paper, closed-form expressions for transient power distribution network (PDN) noise caused by an IC switching current are derived for a PDN structure comprised of traces with decoupling capacitors.

TL;DR: In this article, the concept of target impedance was improved based on the rigorous closed-form expressions for transient supply voltage ripple excited by an integrated circuit (IC) switching current, for the power distribution network (PDN) with power traces that is commonly used in handheld devices.

TL;DR: In this paper, a co-simulation model for secondary ESD inside a portable electronic product is presented, which combines linear descriptions of the ESD generator and the DUT with the nonlinear spark-arc model and a model for the initiation delay (statistical time lag) of the spark.
