Abstract: A device for measuring force components formed from a single crystal material, wherein the device comprises at least one cantilever beam inclined to a wafer plane normal and formed in one piece with a mass body, which mass body provides a mass of inertia. The mass body has a first and a second major surface which are substantially parallel with a wafer plane. A mass body cross section presents a portion which is substantially symmetrical along a centrally (in the thickness direction) located plane parallel with the wafer plane. Disclosed is also a method for its production and an accelerometer comprising at least one such device. The device allow for a more compact 3-axis accelerometer.

Abstract: Certain disclosed accelerometer sensors and methods employ a proof mass that is acted upon by multiple feedback paths. One illustrative sensor embodiment includes an electrode arrangement proximate to a proof mass, the electrode arrangement providing multiple electrostatic force centroids on the proof mass. The sensor embodiment further includes multiple feedback paths, each feedback path independently controlling an electrostatic force for a respective centroid, and an output unit that converts signals from the multiple feedback paths into an acceleration-responsive output signal. An illustrative method embodiment derives multiple feedback signals from at least one displacement signal, applies the multiple feedback signals to an arrangement of electrodes that capacitively couple the proof mass to a substrate, and converts the multiple feedback signals into an acceleration signal.

Abstract: A modulator is provided in operative engagement with a sensor element having a plurality of electrodes. The modulator has a single-bit quantizer electrically connected to a digital accumulator. The accumulator accumulates output information received from the single-bit quantizer. The accumulator converts the accumulated output information received from the single-bit quantizer to a multi-bit feedback signal and sends the multi-bit feedback signal in a primary feedback loop back to the sensor element. The quantizer sends a single-bit feedback signal in a secondary feedback loop back to a point before the quantizer.

Abstract: Provided are a method, system, and device directed to a receive path for a node in a communication system such as a Radio Frequency Identification (RFID) system. In one aspect, the receive path includes a filter operable in multiple modes and configurable to have different bandwidths in the various modes of operation. For example, in one mode, the filter samples a DC component while configured to have a relatively wide bandwidth. As another example, the filter may be operated in another mode to hold the sampled DC component while the filter is configured to have a zero or close to zero bandwidth. As yet another example, the filter may be operated in still another mode to filter received signals and cancel the sampled DC offset from the received signals while configured to have a relatively narrow bandwidth. Additional embodiments are described and claimed.
