Crosstalk reduction in electrical interconnects

Abstract

Embodiments reduce crosstalk between electrical interconnects by offsetting pairs of electrical interconnects in an electrical system to produce a staggered interconnect pattern for which magnetic flux through a loop formed by a victim interconnect pair is effectively canceled. Magnetic field vectors generated by an aggressor pair of interconnects can pass through a loop-bounded surface defined by a victim pair of interconnects in the system. In the staggered interconnect pattern, the victim interconnect pair is offset with respect to the aggressor interconnect pair so that the field vectors passing through the victim pair's loop-bounded surface in one direction are substantially balanced by the field vectors passing through the victim pair's loop-bounded surface in the opposite direction, thereby minimizing the effect of the aggressor pair's magnetic field on the victim pair. Since crosstalk is proportional to the rate of change of the magnetic flux, reducing the magnetic flux can reduce the crosstalk.
