Depending on the PCB fiber weave style, electrically long differential microstrip signal traces may introduce significant signal skew due to weave effect that deteriorates the signal quality. As closed-form expression for the effective permittivity t

A method to estimate the frequency spectrum of IC power supply by measuring transient voltage on Power Distribution Network (PDN) was proposed in this work. The proposed method was validated through measurement on a testing board with three clock dri

Based on measurements from a near-field scanner and far-field measurements obtained in a semi-anechoic chamber, a statistical relationship is established between a magnetic field in the near field and an electric field in the far field. The relations

A method on developing pre-layout PDN model utilizing 3D full-wave simulation was proposed in this work. The proposed method divides the PDN into different blocks and obtains the network parameters of each block using 3D full-wave simulation. The pro

Based on a two-probe inductive coupling approach, a novel measurement method to characterize the impedance of any passive component (R, L, or C) under a direct-current (dc) biasing condition has been developed. With a premeasurement calibration proce

This paper discusses a novel approach to transforming a radiated-emission limit (e.g., CISPR 22 and FCC) from the far-field to the near-field region. The proposed approach combines data from a near-field scanner and a gigahertz transverse electromagn

Today's digital data lines are clocking at very high speed, in excess of 100MHz with rise time in the sub-nano second range. The effects of EMI radiation even from short traces are becoming significant and cannot be ignored. The use of resistive term
