  • Patent number: 11792057
    Abstract: A communication system comprises a transmitter and a receiver that communicate differential phase modulated data over a wireline channel pair. The transmitter encodes data symbols by generating first and second data signals with differentially phase shifted signal transitions with respect to one another. The receiver receives the first data signal and the second data signal and samples the first data signal based on a signal transition timing of the second data signal to generate a first output data symbol. The receiver furthermore samples the second data signal based on signal transition timing of the first data signal to generate a second output data symbol.
    Type: Grant

  • Patent number: 10658987
    Abstract: The embodiments herein describe technologies of an amplifier circuit that is designed for wideband communication with superconductive components in cryogenic applications, including Josephson Junction integrated circuits, operating in a cryogenic temperature domain (e.g., 4K). The amplifier circuit operates in a temperature domain (e.g., 77K) that is higher than the cryogenic temperature domain of the superconductive components.
