Abstract:

The transmission matrix for return path discontinuity is introduced to the transmission matrix model of ideal interconnect, and a new model is presented. Compared with the S-parameter model, the performance of the new model is verified and the accurate coupling crosstalk noise of non-ideal interconnect can be obtained. Finally, the influence of cutout on crosstalk is also studied. Simulation results show that the transmission lines should be placed close to the edge of cutout and that the space between two lines should be as large as possible.

Key words: transmission matrix, crosstalk, S-parameter model, cutout
