  • PRECOMPENSATION TECHNIQUE FOR IMPROVED VCSEL-BASED DATA TRANSMISSION
    Publication number: 20170126327
    Abstract: The present disclosure relates to an apparatus for precompensating a VCSEL-signal, comprising a FIR-filter, wherein the FIR-filter is adapted to precompensate a signal by adjusting a portion of the signal in the first bit after a signal transition, and wherein the precompensated signal is injected into a VCSEL.

  • Board connector
    Patent number: 9459420
    Abstract: A connector mounted on a board. The connector includes one or more elements mounted on the board by means of a cured adhesive, which is at least partly present between the element and at least one anchoring element, E.g., the board mounted element may include one or more holes filled, with the cured adhesive embedding one or more of the at least one anchoring elements. The board mounted element may for instance be an optical coupler.

  • Propagation delay variation for a distributed optical modulator driver
    Patent number: 7317846
    Abstract: Propagation delay variations for a distributed optical modulator driver are described. In one example, a system includes a signal distribution network, a plurality of output driver stages coupled to the signal distribution network, a waveguide coupled to the outputs of the output drive stages to receive a voltage across the waveguide, and a plurality of delay cells between the distribution network and the plurality of output driver stages to apply a differential delay to the output stages.

  • Lower power high speed design in BiCMOS processes
    Patent number: 7126382
    Abstract: A low power high-speed design for integrated circuits using BiCMOS processes is disclosed. The design uses a first stage including bipolar transistor pairs configured as inputs and drivers for an output. A second CMOS stage is coupled to the first stage in a series-gated configuration and receives clock or data inputs. A third stage is coupled to the second stage and is configured as a current source. The combination results in circuits that can operate at conventional supply voltages of 1.8 volts.
