Abstract

Abstract: A simplified electromagnetic interference (EMI) model is given for a multi-pinsconnector based on the assumption of nearest interaction between pins. Method of moments (MOM) is used in the calculation of per unit length capacitances. Theaccuracy of the model for high frequency signals is discussed. Crosstalk betwenpins are simulated in frequency domain and time domain. Simulating results maybe helpful in the decreasing of EMI in connectors.

Key words: connector, method of moments, electromagnetic interfere, frequency domain, time domain
