  • Patent number: 8279951
    Abstract: A method and device are provided for producing a transmission signal to be transferred over a transmission path from an input signal, for example an xDSL signal, wherein a bandwidth of the input signal is distributed onto a plurality of frequency bands in such a way that part signals are obtained corresponding to the individual frequency bands, and wherein each part signal is conducted to separate line drivers, and wherein output signals of the individual line drivers are combined to form the transmission signal to be transferred over the transmission path by combination means, which can be designed as an adder. In order to obtain the frequency band which pertains in each case from the input signal, which can be transformed into an analogue signal with a D/A converter, filter means can be used.

  • Patent number: 8278730
    Abstract: The disclosed invention provides a structure and method for providing a high lateral voltage resistance between the electrical networks, sharing a lateral plane, of conductive elements (e.g., having different high voltage potentials) comprising a coupler. In one embodiment, an integrated coupler providing a high lateral voltage resistance comprises a primary conductive element and a secondary conductive element. An isolating material is laterally configured between the electrical network of the primary conductive element and an electrical network of the secondary conductive element. The isolating material may comprise a low-k dielectric layer and prevents any lateral barrier layers (e.g., etch stop layers, diffusion barrier layers, etc.) from extending between the first conductive element and the electrical network of the second conductive element. The structure therefore provides a galvanically isolated integrated coupler which avoids electrical shorting between circuits (e.g.

  • Patent number: 8278634
    Abstract: A method comprising introducing an injected gas (e.g., Argon, Xenon) into a beam line region comprising a magnetic scanner is provided herein. The injected gas improves beam current by enhancing (e.g., increasing, decreasing) charge neutralization of the magnetic ion beam (e.g., the ion beam at regions where the scanning magnetic field is non-zero) thereby reducing the current loss due to the zero field effect (ZFE). By reducing the current loss in regions having a magnetic field, the magnetic beam current is increased (e.g., the beam current is increased in regions where the magnetic field is non-zero) raising the overall beam current in a uniform manner over an entire scan path and thereby reducing the effect of the ZFE. In other words, the ZFE is removed by effectively minimizing it through an increase in the magnetized beam current.

  • Patent number: 8278892
    Abstract: A converter for converting a DC input voltage includes two input lines receiving the DC input voltage; at least one normally off semiconductor switch which is not conductive without application of a control voltage to its gate and which is provided in one of the input lines. The converter also includes electric circuitry connected between the input lines and including at least one normally on semiconductor switch which is conductive without application of a control voltage to its gate; and a controller. In operation of the converter, the controller operates the at least one normally on semiconductor switch of the electric circuitry by temporarily applying a first control voltage to its gate; and permanently applies a second control voltage to the gate of the at least one normally off semiconductor switch in the one input line. Any normally on semiconductor switch of the electric circuitry is spatially separated and thus thermally isolated from any normally off semiconductor switch.

  • Patent number: 8263450
    Abstract: A semiconductor component with charge compensation structure has a semiconductor body having a drift path between two electrodes.

  • Patent number: 8258880
    Abstract: Some embodiments disclosed herein relate to techniques for providing a relatively constant oscillation frequency. In some instances, these techniques can make use of a ring oscillator that is powered by an adaptive voltage supply. The adaptive voltage supply provides a temperature-dependent supply voltage to respective delay elements in the ring oscillator, such that the oscillation frequency of the ring oscillator is approximately constant over a predetermined temperature range. For example, if temperature increases, the supply voltage can be increased proportionally, thereby tending to limit variation in the oscillation frequency delivered by the ring oscillator.
