    In recent years, as the density of the components in the integrated circuit grows, the distance between the on-chip wires becomes smaller. The crosstalk is more important and will change the signal waveform or generate logic failures and then degrade the performance and the reality of the circuit. In this paper, we focus on the response of the transmission line and the value of the crosstalk noise... View full abstract»
