Abstract: An embodiment of the invention relates to a temperature-sensing device and a related method. In an embodiment, the device senses a temperature with a first sensing circuit configured to assert a signal when temperature is above a first temperature threshold level, and a second sensing circuit configured to substantially disable a bias current that powers the first sensing circuit when a sensed level of temperature is below a second, lower temperature threshold level. Accordingly, the device is able to draw substantially reduced current from a power source when the sensed temperature level is less than the second threshold level. Other physical parameters such as strain or pressure may also be sensed using the same technique.

Abstract: The invention relates to a semiconductor component with stress-absorbing semiconductor layer (SA) and an associated fabrication method, a crystalline stress generator layer (SG) for generating a mechanical stress being formed on a carrier material (1). An insulating stress transmission layer (2), which transmits the mechanical stress which has been generated to a stress-absorbing semiconductor layer (SA), is formed at the surface of the stress generator layer (SG), with the result that in addition to improved charge carrier mobility, improved electrical properties of the semiconductor component are also obtained.

Abstract: Some embodiments of the present disclosure relate to multiband receivers that include at least one divider unit having a divisor that is other-than-two. For example, in some embodiments the divisor is an odd integer (e.g., three). Such divisors allow oscillators for respective receiver subunits in a multi-band receiver to have frequencies that are sufficiently different from one another so as to limit cross-talk interference there between, even when the receiver subunits are concurrently receiving data on adjacent channels. To facilitate this other-than-two divisor, a phase error compensation block is often used to compensate for the effects of using the other-than-two divisor.
Abstract: An apparatus for detecting an error within a coded binary word includes an error corrector and an error detector. The error corrector corrects a correctable bit error within a faulty subset of bits of a faulty coded binary word coded by an error correction code, so that the corrected subset of bits is equal to a corresponding subset of bits of a code word of the error correction code, if the error corrector works faultlessly. Further, the error detector determines an error detection bit sequence indicating whether or not an error detector input binary word is a code word of the error correction code. The error detector input binary word is based on a corrected coded binary word containing the corrected subset of bits and maximally a proper subset of bits of the faulty coded binary word.

Abstract: One embodiment of the present invention relates to an adaptive filtering apparatus comprising first and second real valued adaptive filters, respectively configured to receive an adaptive filter input signal based upon a transmission signal in a transmission path. The first real valued adaptive filter is configured to operate a real valued adaptive filter algorithm on the input signal to estimate a first intermodulation noise component (e.g., an in-phase component) in a desired signal and to cancel the estimated noise. The second real valued adaptive filter is configured to operate a real valued adaptive filter algorithm on the input signal to estimate a second intermodulation noise component (e.g., a quadrature phase component) in the desired signal and to cancel the estimated noise. Accordingly, each filter operates a real valued adaptive algorithm to cancel a noise component, thereby removing complex cross terms between the components from the adaptive filtering process.

Abstract: Disclosed is a power regulator for providing precisely regulated power to a microelectronic device such as a microprocessor. Improved power regulation is accomplished by optimizing the power efficiency of the power regulator. In particular, in a multiphase system, the number of active phases is increased or decreased to achieve optimum power efficiency. The multiphase voltage regulator adapts the operating mode to maximize efficiency as the load current demand of the load device changes by adjusting the number of active phases to maximize efficiency. The total value of current provided by the regulator and the total number of active phases is determined, the total number of active phases is compared with the number of active phases required to provide the total value of current at maximum efficiency; and the number of active phases is adjusted to provide the total value of current at maximum efficiency.
