20120200326 | Method and Apparatus for Reducing Signal Edge Jitter in an Output Signal from a Numerically Controlled Oscillator - A method for reducing signal edge jitter in an output signal from a numerically controlled oscillator includes processing an input signal with a first accumulator to provide a first accumulator output signal and continuing to use a carry in the processing of the input signal with the first accumulator in the event of an overflow. The method further includes processing the input signal with a second accumulator to provide a second accumulator output signal and rejecting a carry in the processing of the input signal with the second accumulator in the event of an overflow. The method further includes outputting the second accumulator output signal at an output of the numerically controlled oscillator and synchronizing the second accumulator using the first accumulator output signal. | 08-09-2012 |
20130098154 | Piezoresistive Micromechanical Sensor Component and Corresponding Measuring Method - A piezoresistive micromechanical sensor component includes a substrate, a seismic mass, at least one piezoresistive bar, and a measuring device. The seismic mass is suspended from the substrate such that it can be deflected. The at least one piezoresistive bar is provided between the substrate and the seismic mass and is subject to a change in resistance when the seismic mass is deflected. The at least one piezoresistive bar has a lateral and/or upper and/or lower conductor track which at least partially covers the piezoresistive bar and extends into the region of the substrate. The measuring device is electrically connected to the substrate and to the conductor track and is configured to measure the change in resistance over a circuit path which runs from the substrate through the piezoresistive bar and from the piezoresistive bar through the lateral and/or upper and/or lower conductor track. | 04-25-2013 |
