    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.

    Abstract: A system is provided for transmitting sub-terahertz electro-magnetic radio frequency (RF) signals using a dielectric waveguide (DWG) having a dielectric core member surrounded by dielectric cladding. An RF transmitter is coupled to an antenna located on a first substrate, in which the antenna is adjacent an edge of the substrate. The first substrate is mounted on a second substrate. A conductive reflector plate is formed on the top surface of the second substrate. An end of the DWG is mounted on the second substrate over the reflector plate such that an exposed face of the core member at the end of the DWG is adjacent the antenna. The core member at the end of DWG forms an angle of inclination with the second substrate in which the angle is in a range of approximately 10-30 degrees.

    Abstract: Data transfer devices and methods for transferring data between first and second circuits are disclosed. A data transfer device includes a first circuit having a plurality of data channels, wherein at least one of the data channels is an active data channel. A serializer has a plurality of inputs and an output, wherein the inputs are coupled to the plurality of data channels. The serializer is for coupling only one active channel at a time to the output. An isolation barrier is coupled to the output of the serializer, the isolation attenuates transients and passes the fundamental frequency. A second circuit includes a deserializer having an input and at least one output, the input is coupled to the isolation barrier, the at least one output is at least one active data channel.
