摘要： A sensor for capacitive detection of a mechanical deflection includes a substrate having a first substrate electrode and a second substrate electrode; and a mass movable relative to the substrate. The mass is divided into: a first electrically separate region having a first ground electrode; and a second electrically separate region of the mass having a second ground electrode. At least one portion of the first ground electrode is situated in a first region between the first substrate electrode and the second substrate electrode, and forms a first differential capacitor. At least one portion of the second ground electrode is situated in a second region between the first substrate electrode and the second substrate electrode, and forms a second differential capacitor.

摘要： 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.
