Abstract :
Crosstalk noise, which leads malfunction in data transmission equipment, is one of the most important problems to be solved. In this study, a CMOS-IC, a silicon diode, and a variable capacitance diode are used as nonlinear loads of microstrip lines. The waveform of the far-end crosstalk is measured and analyzed using a 4-port network model in the time domain. It is shown that the C-V characteristics of the diodes influence the waveform of the crosstalk, and that it is valid to calculate the waveform considering the capacitance of the loads to be fixed if the dependence of the capacitance upon the voltage is small
