Comparing Various Measurement and Simulation Techniques for Estimating Crosstalk

Abstract

A comparison between crosstalk measurement techniques is made to investigate their applicability and efficiency for determining crosstalk between cables above a ground plane made of copper or carbon-fibre reinforced plastic (CFRP). Cost effectiveness, accuracy, speed and complexity of the methods are evaluated. All measurements are performed on two PCBs containing two pairs of copper traces. The techniques that are considered include balanced Vector Network Analyzer (VNA) measurements, balanced Spectrum Analyzer (SA) measurements, balanced EMI receiver (EMI-R) measurements, single-ended VNA measurements converted to mixed-mode S-parameters, and finally measurements with a signal generator (SG) and an oscilloscope (OSC). For verification, measured results are also compared to three simulation techniques, involving a Method of Moments simulation and two different transmission line models.

“…The resulting output signal will be dependent on this input signal and the transfer function H(ω) (Fig. 2c), which has a slope of 20 dB for lower frequencies as long as the cable is electrically short [9]. In Accordance to [8], for a nearfield coupling the output signal envelope would present a trapezoidal format, with both slopes at a 20 dB rate (Fig.…”

“…Results were also compared to three simulation techniques for verification. The study aims to improve crosstalk detection in cables [8].…”

Evaluation of Nonlinear ARX System Identification Technique on Modeling Crosstalk

“…Furthermore, to predict crosstalk in a circuit, an appropriate model is needed. Previous studies have accurately modelled crosstalk such as the multi-conductor transmission line (MTL) [1], [6], [7], the Spice-based SACAMOS [8], the finite-difference time-domain (FDTD) [9], and the equivalent circuit model [10], [11]. However, to obtain good accuracy, these models need detailed information of the actual circuit.…”
