    Abstract: A circuit for receiving digital signals over a transmission line. A feedback circuit is coupled to an input node of the transmission line and adjusts the input impedance of the receiver circuit to match the characteristic impedance of the transmission line. The feedback circuit includes a first current source controlled by a first voltage and having a first transconductance, and a second current source controlled by the first voltage and having a second transconductance equal to the first transconductance times a first scaling factor. The feedback circuit includes a first resistance element having a resistance equal to the first scaling factor plus one, times the characteristic impedance of the transmission line, and is coupled between the outputs of the first and second current sources.

  • Publication number: 20130327792
    Abstract: The present invention relates to apparatus and method for re-circulating high viscosity liquids. The apparatus comprises a recirculating probe coupled to a fluid storage and dispensing vessel by a connector, and the recirculating probe comprises: (a) a dip tube defining an output flow path; (b) an output port; (c) a recirculating port; and (d) a return flow path. The output flow path and the return flow path preferably have substantially equal cross-sectional areas, which reduce or eliminate the unbalance between the discharge pressure in the output line and that in the re-circulation line, and prevent premature wearing-out of the dispensing/recirculating pump.

  • Patent number: 8470400
    Abstract: Processes for synthesizing graphene films. Graphene films may be synthesized by heating a metal or a dielectric on a substrate to a temperature between 400° C. and 1,400° C. The metal or dielectric is exposed to an organic compound thereby growing graphene from the organic compound on the metal or dielectric. The metal or dielectric is later cooled to room temperature. As a result of the above process, standalone graphene films may be synthesized with properties equivalent to exfoliated graphene from natural graphite that is scalable to size far greater than that available on silicon carbide, single crystal silicon substrates or from natural graphite.

  • Publication number: 20130026444
    Abstract: A method and semiconductor device for synthesizing graphene using ion implantation of carbon. Carbon is implanted in a metal using ion implantation. After the carbon is distributed in the metal, the metal is annealed and cooled in order to precipitate the carbon from the metal to form a layer of graphene on the surface of the metal. The metal/graphene surface is then transferred to a dielectric layer in such a manner that the graphene layer is placed on top of the dielectric layer. The metal layer is then removed. Alternatively, recessed regions are patterned and etched in a dielectric layer located on a substrate. Metal is later formed in these recessed regions. Carbon is then implanted into the metal using ion implantation. The metal may then be annealed and cooled in order to precipitate the carbon from the metal to form a layer of graphene on the metal's surface.

  • Publication number: 20110317786
    Abstract: Systems and methods for identifying a transmission channel response and a feedback channel response from a plurality of composite system responses are disclosed. A plurality of shifted feedback signals are created by shifting a feedback signal frequency by a plurality of first offset values and/or by shifting a transmission signal frequency by a plurality of second offset values. The feedback signals are compared to an input signal to identify the transmission channel response and/or a feedback channel response. A control signal is generated for a pre-distortion circuit to modify the input signal by an inverse of the transmission channel response. The composite system response is measured at a plurality of operating frequencies and at the plurality of offset values. The measurements are stored in a matrix and singular value decomposition is applied to the matrix of measurements to calculate the transmission channel response and feedback channel response.

  • Publication number: 20110314310
    Abstract: A system and method are disclosed for capturing pre- and post-event data for random events using minimum power. Real-time data is captured and stored in a continuous loop in a segment of a first memory. Upon detection of a designated event, a second memory is powered-on and post-event data is stored to a segment of the second memory. After a designated data capture window, the second memory is powered-off and real-time data is captured in an unused segment of the first memory. The post-event data may be captured in the unused segment of the first memory and later transferred to the second memory. Auto-address logic monitors and controls the storage and retrieval of pre- and post-event in the first and second memory. An energy management system determines and controls which segments of the first and second memory should be powered-on or kept in the stasis mode to store event data.

  • Publication number: 20100278065
    Abstract: Embodiments of the invention comprise a system and method for estimating a traffic load on a wireless network. An access point notifies a station that the access point will not receive transmissions during a first quiet period. After the first quiet period, the access point monitors the wireless network during a first monitoring period. If no transmissions are received during the first monitoring period, the access point notifies the station that it will not receive transmissions during a second quiet period. The second quiet period has an equal or longer duration than the first quiet period. The access point alternates between monitoring periods and quiet periods and progressively expands the duration of the quiet periods as long as no transmissions are received during the monitoring periods. If a station notifies the access point that packets are pending at the device, the monitoring period is extended to handle these packets immediately.

  • Publication number: 20100228515
    Abstract: A method of generating multi-frame test signals, a testing apparatus, and method for testing integrated circuits (ICs) with the multi-frame test signals. An analog source generates an analog source signal at a constant power and a constant frequency that is modulated with a first modulating signal (e.g., I) to output a first test signal having first signal parameters including a power level, a frequency and a modulation scheme. The modulating is repeated with a second modulating signal (e.g., Q) to output a second test signal having second signal parameters including a power level, a frequency and a modulation scheme. At least one of the first and second signal parameters are different. The modulating signals are generated by a digital signal source. The first and second test signal are combined by placing the first test signal on the first frame (frame 1) and the second test signal on the second frame (frame 2) of the multi-frame test signal.
