Embodiments of the present disclosure are directed toward techniques and configurations for electrical signal absorption in an interconnect stub. In one instance, a printed circuit board (PCB) assembly may comprise a substrate and an interconnect (such as a via) formed in the substrate to route an electrical signal within the PCB. The interconnect may include a stub formed on the interconnect. At least a portion of the stub may be covered with an absorbing material to at least partially absorb a portion of the electric signal that is reflected by the stub. The absorbing material may be selected such that its dielectric loss tangent is greater than one, for a frequency range of a frequency of the reflected portion of the electric signal. A dielectric constant of the absorbing material may be inversely proportionate to the frequency of the reflected electric signal. Other embodiments may be described and/or claimed.

Reflected signal absorption in interconnect

Apparatuses and methods associated with shield lines, and/or complementary decoupling capacitors and/or electromagnetic absorbing materials are disclosed herein. In embodiments, an apparatus may include a substrate having a ground plane; and a first and a second transmission line disposed on the substrate. Further, the apparatus may include a shield line constituted with electromagnetic absorbing material disposed between the first and second transmission lines and not coupled with the ground plane. In embodiments, the substrate may further include a power plane having a plurality of edges and a plurality of spacing; a plurality of decoupling capacitors disposed on the power or ground plane; and electromagnetic absorbing materials adhered to the plurality of edges and disposed in the plurality of spacing. Other embodiments may be described and/or claimed.

Crosstalk, power supply noise and/or EMI reduction methods and apparatuses

A micro-strip transmission line may include a plurality of conductors, wherein each conductor has a compensating portion and a remaining portion. The compensating portion can compensate for far-end crosstalk in the remaining portion. In one example, the compensating portion has a longitudinal section and a plurality of alternating stubs extending from lateral surfaces of the longitudinal section.

Micro-strip crosstalk compensation using stubs

In some embodiments, an circuit card includes an electronic circuit substrate, a ground plane on the electronic circuit substrate, first and second differential signal pads on the electronic circuit substrate, a ground return signal pad associated with the first and second differential signal pads, the ground return signal pad being connected to the ground plane on the electronic substrate, and a cutout structure on the ground plane positioned near a location where the ground return signal pad connects to the ground plane, wherein the cutout structure is configured to direct a ground return path associated with the first and second differential signal pads to the ground return signal pad associated with the first and second differential signal pads. Other embodiments are disclosed and claimed.

Connector having a cut-out for reduced crosstalk between differential conductors

Compounds comprising multi-vitamins, zinc and an anti-platelet aggregating agent for the treatment of atherosclerotic cardiovascular disease (ASCVD) are disclosed. The compounds are provided in dosage form, and preferably include selected amounts of ascorbic acid, folic acid, vitamin E, vitamin B6 and vitamin B12. The anti-platelet aggregating agent preferably comprises aspirin. A protective coating is preferably provided between the aspirin and the other vitamin and mineral constituents. The dosages are effective in the treatment of ASCVD, and possess extended shelf lives.
