    Abstract: A double Schottky-barrier diode includes a semi-insulating substrate, a left mesa formed by growth and etching on the semi-insulating substrate, a middle mesa formed by growth and etching on the semi-insulating substrate, a right mesa formed by growth and etching on the semi-insulating substrate, two anode probes and two air-bridge fingers. The two Schottky contacts are closely fabricated on the same mesa (middle mesa) in a back-to-back manner to obtain even symmetric C-V characteristics and odd symmetric I-V characteristics from the device level. The output of a frequency multiplier fabricated using the double Schottky-barrier diode only has odd harmonics, but no even harmonics, which is suitable for the production of high-order frequency multipliers. The cathodes of the two Schottky contacts are connected by the buffer layer without ohmic contact.

  • Publication number: 20210218604
    Abstract: Data symbols in an input signal are detected with a slicer of a DFE of a transceiver device. An output of a feedback filter of the DFE is generated, during a particular clock cycle, based on a first set of one or more data symbols detected during first one or more previous clock cycles and a second set of one or more data symbols detected during second one or more previous clock cycles. The second set is separated from the first set by a third set of one or more data symbols detected during third one or more clock cycles that occur after the first one or more clock cycles and before the second one or more clock cycles, where the output is generated without use of the third set of symbols. The output is subtracted from the input signal to generate an equalized input to the slicer.
