Abstract: Circuits, methods, and apparatus that provide improved data encoding for data transmitted through a channel of limited bandwidth. One example can provide circuits, signaling methods, and apparatus that can encode data to more fully utilize a bandwidth of a physical channel. This encoding can help to increase a data rate through the physical channel.

Abstract: Circuits, methods, and apparatus that may reconstruct a data signal in the presence of ground drift and high-frequency signal coupling. An illustrative embodiment of the present invention may reconstruct a received data signal by taking an finite difference of the received data signal, detecting edges of the received data signal by detecting positive and negative peaks of the finite difference of the received signal, and reconstructing the received data signal using the detected edges. Taking a finite difference of the received data signal removes the DC component of the received data signal, as well as the ground drift that may cause the DC component of the received data signal to change over time. Additional filtering may be used to reduce high-frequency signal coupling and power supply inductive coupling.

Abstract: Connector inserts and receptacles that provide signal paths having desired impedance characteristics. One example may provide a connector system having a connector insert and a connector receptacle. Contacts in the connector insert may form signal paths with corresponding contacts in the connector receptacle. Additional traces in the connector insert and receptacle may be part of these signal paths. The signal paths may have a target or a desired impedance along their lengths such that the power paths electrically appear as transmission lines. Constraints on physical dimensions of the connector insert and connector receptacle contacts may result in variations in impedance along the signal paths. Accordingly, embodiments of the present invention may provide structures to reduce these variations, to compensate for these variations, or a combination thereof.

Abstract: The described embodiments relate generally to a dielectric wave guide interconnect for an electronic device including a first routing circuit, a second routing circuit, and a dielectric wave guide coupling the first routing circuit to the second routing circuit. The interconnect may also include a first coupling element securing a first end of the dielectric wave guide proximal to the first routing circuit and a conductive element to insulate the dielectric wave guide from radio-frequency (RF) signals. In some embodiments, the first routing circuit is in a bottom portion of the electronic device; and the second routing circuit is in a top portion of the electronic device. An electronic device including a dielectric wave guide interconnect as above is also disclosed. A coupler for an electronic device including a first end adapted to receive an electrical signal and a propagating electromagnetic signal is also disclosed.
