Abstract

A theoretical model for the electrical characterization of multi-pin modular daughterboard-to-backplane connectors at high bit rate signals is developed. The fundamental field equations are transformed into a linear system of equations for the currents and voltages at the edges of the pins of the connector.Efficient formulaes for the calculation of self and mutual inductances and capacitances between the pins which are involved in the linear system of equations are obtained. Using the previous developed theoretical model the connector's performance can be examined in both the frequency and the time domain.Numerical calculations are performed for three types of existing connectors. Furthermore, they are compared to each other for bit-rates in the range of 100 Mbits/sec up to 500 Mbits/sec.
