20080205488 | Differential Phase Coding in Wireless Communication System - In a wireless communications system, such as a multiband Ultra Wideband communications system, data is tranmitted by means of the phases of pulses in multiple frequency bands. Data is encoded in the phase difference between a pulse and a previously transmitted pulse. The previously transmitted pulse may be the immediately preceding pulse in the same frequency band, or may be separated from the present pulse by a number of intervening pulses. | 08-28-2008 |

20090287493 | DIRECT STREAM DIGITAL AUDIO WITH MINIMAL STORAGE REQUIREMENT - An audio coding scheme allowing PCM signal to lossless DSD signal expansion for next generation optical disc formats. The method of encoding an input DSD signal includes up-sampling a corresponding PCM signal to the DSD sample rate. Then a set of loop filter parameters for a noise-shaping loop of a sigma-delta modulator are generated, either using a random starting condition of the sigma-delta modulator or including synchronization parameters. This will allow a decoder to regenerate an almost perfect signal, but still it needs a correction signal to be able to bit identically regenerate the DSD input signal. Therefore, a correction signal is generated based on a difference between a sigma-delta modulated version of the up-sampled PCM signal and the input DSD signal, wherein the sigma-delta modulated version of the up-sampled PCM signal is obtained using the set of loop filter parameters. The correction signal may be adapted to be applied to the low bit PCM signal, to the up-sampled PCM signal or to the output bit stream. Finally, an expansion bit stream is generated where an encoded version of the set of loop filter parameters and an encoded version of the correction signal are included. The decoder can reproduce the original DSD signal based on the already available PCM signal and the described expansion bit stream. Thus, the coding scheme enables top quality audio with minimal storage overhead since the already available PCM signal is used in combination with an expansion bit stream. Since only an additional data stream is required to be stored on a disc, e.g. as part of an MPEG stream, DSD functionality is added to existing systems without causing compatibility problems. | 11-19-2009 |
20100244189 | INTEGRATION SUBSTRATE WITH A ULTRA-HIGH-DENSITY CAPACITOR AND A THROUGH-SUBSTRATE VIA - An integration substrate for a system in package comprises a through-substrate via and a trench capacitor wherein with a trench filling that includes at least four electrically conductive capacitor-electrode layers in an alternating arrangement with dielectric layers. —The capacitor-electrode layers are alternatingly connected to a respective one of two capacitor terminals provided on the first or second substrate side. The trench capacitor and the through-substrate via are formed in respective trench openings and via openings in the semiconductor substrate, which have an equal lateral extension exceeding 10 micrometer. This structure allows, among other advantages, a particularly cost-effective fabrication of the integration substrate because the via openings and the trench openings in the substrate can be fabricated simultaneously. | 09-30-2010 |

20110128111 | PLANAR, MONOLITHICALLY INTEGRATED COIL - The present invention provides a means to integrate planar coils on silicon, while providing a high inductance. This high inductance is achieved through a special back- and front sided shielding of a material. In many applications, high-value inductors are a necessity. In particular, this holds for applications in power management. In these applications, the inductors are at least 5 of the order of 1 μH, and must have an equivalent series resistance of less than 0.1 Ω. For this reason, those inductors are always bulky components, of a typical size of 2×2×1 mm 3, which make a fully integrated solution impossible. On the other hand, integrated inductors, which can monolithically be integrated, do exist. However, these inductors suffer either from low inductance values, or 10 very-high DC resistance values. | 06-02-2011 |
