“…In electrical interconnection, microstrip lines are often used as interconnection structures. Crosstalk between microstrip lines is extensively investigated, but most of the studies focus on crosstalk analysis or crosstalk-reduction design between parallel microstrip lines [5][6][7][8]. However, in an actual interconnection design, there is few scenarios in which only parallel microstrip lines are used for layout design.…”

Complex interconnection structure is a common structure on printed circuit board (PCB). Herein, the paper proposes a method of crosstalk cancellation point at the crosstalk problem between microstrip lines in a complex interconnection structure. First, a model of the coupled transmission lines-channel transmission matrix (CTL-CTM) of the complex interconnection structure is established. Second, the CTL-CTM is simplified through the equivalence of crosstalk-coupling coefficient of parallel coupling microstrip lines to that of the complex interconnection structure. The eigenvalue of the simplified CTL-CTM is then decomposed, based on which the construction of crosstalk cancellation circuit is performed. Simulation results show that the proposed method can effectively improve the quality of eye patterns on complex interconnection structures.

“…3 Although this method has a good ability to improve crosstalk, it wastes limited wiring space and does not conform to the development direction of integration. In the articles, [4][5][6] the crosstalk is improved by placing a via-stitch guard or a serpentine guard trace between multiple transmission lines, and the effect of improving the crosstalk is analyzed by EM simulation. The complex structure and possible resonance problems of this method make it difficult to apply and generalize this method in practice.…”

Aiming at the problem of far‐end crosstalk between microstrip lines, a method to improve crosstalk by using the TL‐shaped defective microstrip structure (DMS) is proposed. This method optimizes the ratio of the capacitive coupling and the inductive coupling between coupled microstrip lines by etching TL‐shaped DMSs on the microstrip lines, reducing the strength of electromagnetic coupling, thereby achieving an improvement in crosstalk. The quantitative equivalent model, S‐parameters, and full‐wave EM simulations are used to analyze the frequency response of the TL‐shaped DMS and crosstalk between the microstrip lines. The results of High Frequency Structure Simulator software simulation and sample texts show that the TL‐shaped DMS can effectively improve the far‐end crosstalk while ensuring the transmission of signals on the microstrip line. In the frequency range of 0–8 GHz, the far‐end crosstalk can be improved by about 11 dB, and the maximum can be improved by 42 dB. Compared with other DMSs, the TL‐shaped DMS has better crosstalk improvement effect and practical application potential.

Non-parallel microstrip lines are a layout often used in high-speed interconnections. This study initiates crosstalk reduction by interdigital capacitor for the non-parallel microstrip lines. This method reduces the far-end crosstalk by adding capacitive coupling to cancel inductive coupling after an interdigital capacitor is added at the near end of the non-parallel microstrip lines. Software simulation and actual measurement results show that the proposed method can effectively reduce the far-end crosstalk in non-parallel microstrip lines. The method is also easy to implement and in low cost.
