  • Publication number: 20180175835
    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.

  • Patent number: 9973220
    Abstract: Isolation circuits for digital communications and methods to provide isolation for digital communications are disclosed. An example isolation circuit includes an isolation barrier, a burst encoder in a first circuit, and an edge pattern detector in a second circuit. The example isolation barrier electrically isolates the first circuit from the second circuit. The example burst encoder generates a first pattern in response to receiving a rising edge on an input signal and generates a second pattern in response to receiving a falling edge on the input signal. The example edge pattern detector detects the first pattern or the second pattern received from the burst encoder via the isolation barrier, sets an output signal at a first signal level in response to detecting the first pattern, and sets the output signal at a second signal level in response to detecting the second pattern.

  • Patent number: 9716302
    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.

  • Patent number: 9425808
    Abstract: A frequency detection technique includes generating first and second signals such that a frequency of the first signal is the same as a frequency of the second signal and such that the second signal is phase-shifted by a fixed amount with respect to the first signal. The technique further includes generating a third signal having a frequency that corresponds to an absolute value of a difference between the frequency of the first signal and an integer multiple of a frequency of the reference signal. The technique further includes generating a fourth signal having a frequency that corresponds to an absolute value of a difference between the frequency of the second signal and an integer multiple of the frequency of the reference signal. The technique further includes generating an fifth signal indicative of whether a phase relationship between the third and fourth signals is a leading phase relationship, a lagging phase relationship, or an in-phase relationship.
