摘要: In this work, a new design approach for realizing printed circuit board (PCB) trace configuration with continuous impedance perturbation to reduce crosstalk in PCB interconnects is investigated. The purpose far-end without incorporating additional components order modify the reactive couplings between adjacent traces, however at expense of available frequency band. This achieved by replacing uniform victim on continuously varying-impedance that exhibits lowpass filter characteristic. A simplified proposed profile which governed truncated fourier series presented. shows better reduction results compared conventional intervening guard schemes. Several configurations were designed, implemented, and tested demonstrate advantages underlying principle.
