摘要： An isolated-ADC and a method for providing isolated analog-to-digital conversion are disclosed. The isolated-ADC includes a microelectromechanical system (MEMS), a comparator, and a digital-to-analog converter (DAC). The MEMS includes a beam element supported from a substrate for movement with respect to an axis, first and second actuators and a sensor. The first and second actuators are capable of exerting respective forces upon the beam element causing the beam element to move in response to analog input and feedback signals, respectively. The sensor detects changes in position of the beam element and produces a position signal indicative thereof. The comparator generates a digital signal based upon a comparison of the position signal with a reference value. Based on the digital signal, the DAC generates the feedback signal, and the isolated-ADC produces a digital output signal.

摘要： A microelectromechanical system (MEMS) strain gauge includes at least one flexible arm that can be caused to oscillate. Transverse strain on the arm changes the resonant frequency of the arm. A detector communicating with the flexible arm may detect the frequency of oscillation to provide, an indication of the transverse strain of the substrate.

摘要： A method is presented for fabricating an electrically isolated MEMS device having a conductive outer MEMS element, and an inner movable MEMS element spaced apart from the conductive outer MEMS element. The inner element includes a nonconductive base having a plurality of conductive structures extending therefrom. The conductive components are formed by plating a conductive material into a pre-formed mold which defines the shape of the conductor.

摘要： A method for fabricating MEMS structure includes etching a recess in an upper surface of a substrate that is bonded to a wafer that ultimately forms the MEMS structure. Accordingly, once the etching processes of the wafer are completed, the recess facilitates the release of an internal movable structure within the fabricated MEMS structure without the use of a separate sacrificial material.

摘要： A method for fabricating an electrically isolated MEMS device having an outer stationary MEMS element and an inner movable MEMS element is provided that does not use a sacrificial layer. Rather, a pair of spacers are defined on the outer portions of the upper surface of a conductive wafer, and an insulating material is deposited thereon. The spacers are attached to a substrate to define an internal void therein. The wafer is then patterned to form the outer MEMS element as well as a conductive member for the inner MEMS element, separated from the outer MEMS element by a gap. A portion of the insulating layer that is disposed in the gap is then removed, thereby releasing the inner MEMS element from the stationary MEMS element.
