A FAST APPROACH FOR SIMULATING LONG-TIME RESPONSE OF HIGH-SPEED DISPERSIVE AND LOSSY INTERCONNECTS TERMINATED WITH NONLINEAR LOADSBy C.-N. Chiu and I.-T. ChiangAbstract: This paper presents an efficient approach for analyzing the longtime response of high-speed dispersive and lossy interconnects terminated with nonlinear loads. In this approach, a fast real-time convolution algorithm with computational cost st O(N log2N) is suggested to tackle the long-time analysis of the high-speed dispersive and lossy interconnects, which are modeled by S-parameters. In addition, the acquirement of the S-parameters is recommended to adopt wideband closed-form formulas. The time response of a microstrip line with a nonlinear load is shown as a practical example. The dominant parameters affecting the response of this microstrip line is observed and discussed in detail. The approach demonstrates its efficiency and accuracy in the analysis.
