Analysis of far-end crosstalk using two parallel microstrip lines considering C-V characteristics

摘要

The high-speed and large-capacity digital communication has been required to date. The crosstalk noise is one of the most important problems to be solved, which leads malfunction in data transmission equipments. In this study, a silicon diode and a variable capacitance diodes are used as nonlinear loads of the microstrip lines. The waveform of the far-end of crosstalk is measured and analyzed using a 4-port network model in the time domain. It is shown that the c-v characteristics of diode influences the waveform of the crosstalk and that it is valid to calculate the waveform considering the capacitance of the loads to be constant, if the dependence of the capacitance upon the voltage is small.
