%X <p>In high-speed circuit, crosstalk is one of the bottlenecks hindering system rate to continue rising. In a 50-Ohm bus, with a spacing equal to the line width, 95% of all the crosstalk on any victim line comes from the nearest two traces on either side of the victim line. However, the current methods only consider the crosstalk from the first nearest traces, which means the crosstalk can be suppressed 75% at most. In order to solve the crosstalk from the second nearest traces, a new circuit structure was proposed, in which the position and the number of inverters could be changed according to the principle of crosstalk phase cancellation to suppress the crosstalk from the nearest two traces at same time. Simulation shows that in range of 0.1~4 GHz, far crosstalk from the second nearest trace can be eliminated about 10 dB.</p>
