Abstract: Described examples include an integrated circuit including a receive portion to receive an encoded transmission on a line. The receive portion has: a wake mode in which the receiver is capable of receiving the encoded transmission; and a sleep mode in which the receiver is not capable of receiving the encoded transmission. A wakeup controller monitors the line for a wakeup signal and provides a signal to the receive portion to cause the receive portion to enter the wake mode when the wakeup controller receives the wakeup signal.

Abstract: An interposer that acts as a buffer zone between a transceiver IC and a dielectric waveguide interconnect is used to establish two well defined reference planes that can be optimized independently. The interposer includes a block of material having a first interface region to interface with an antenna coupled to an integrated circuit (IC) and a second interface region to interface to the dielectric waveguide. An interface waveguide is formed by a defined region positioned within the block of material between the first interface region and the second interface region.

Abstract: A regenerative differential receiver includes, for example, a transformer arranged to receive a modulated differential signal. A first detector is arranged to source a first output current for indicating a first power level in response to falling voltage of a first line of the modulated differential signal. A second detector is arranged to sink a second output current for indicating a second power level in response to rising voltage of a first line of the modulated differential signal. A cross-coupled latch is arranged to latch a state in response to the first and second power levels. The cross-coupled latch provides, for example, weak non-linear regeneration for increasing receiver gain and maximum operating frequencies.

Abstract: A system is provided in which a set of modules each have a substrate on which is mounted a radio frequency (RF) transmitter and/or an RF receiver coupled to a near field communication (NFC) coupler located on the substrate. Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a field confiner located between the NFC coupler and the port region on the housing configured to guide electromagnetic energy emanated from the NFC coupler through the port region to a port region of an adjacent module. The port region is offset laterally from the NFC coupler. The field confiner is skewed to provide a pathway between the NFC coupler and the port region.

Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a tapered near field communication (NFC) field confiner located between the substrate and the port region on the housing configured to guide electromagnetic energy produced by the RF transmitter to the port region so that it can be emanated to a port region of an adjacent module.

Abstract: A system is provided in which a first waveguide has a first resonator coupled to an end of the first waveguide. A second waveguide has a second resonator coupled to the second waveguide. The first resonator is spaced apart from the second resonator by a gap distance. Transmission of a signal propagated by the first waveguide across the gap to the second waveguide is enhanced by a confined near field mode magnetic field produced by the first resonator in response to the propagating wave that is coupled to the second resonator.
