Crosstalk Analysis for High-Speed Pulse Propagation on Frequency-Dependent Lossy Electrical Interconnections

Frequency-domain expressions for coupled transmission lines with triangular input waveforms are first developed. The inverse Fourier transformation (IFFT) and an accelerated inverse Laplace transformation (AILT) are then used to obtain the time-domain triangle impulse responses (TIR). Compared with the IFFT, AILT needs much less CPU running time. The triangle impulse responses can then be used in a time-domain convolution approach to accurately and efficiently simulate the crosstalk of frequency-dependent lossy electrical interconnections.
