    Abstract: Apparatuses and methods including conductive vias of a printed circuit board are described. An example apparatus includes a first layer including a first conductive plate; a component on the first layer, a second layer including a second conductive plate that may be coupled to an external power source; a third layer between the first layer and the second layer, the third layer including a third conductive plate; a first via coupling the first conductive plate to the second conductive plate; and a second via coupled to the first conductive plate. The first conductive plate includes a first portion coupled to the first via and the first conductive plate further includes a second portion coupled to the second via between the first portion and the component. The second via is coupled to either the second conductive plate or the third conductive plate.

    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.
