The method comprises applying a first alternating voltage signal to the actuation electrode, wherein an actuation force is generated having a frequency bandwidth that is greater than and includes a resonant bandwidth of a mechanical frequency response of the resonator, and wherein a displacement of the resonator is produced which is filtered by the mechanical frequency response and varies a value of an electrical characteristic of the first detection electrode. The method also comprises applying a second alternating voltage signal to the first detection electrode, wherein the second voltage signal is mixed with the varying value to produce a first alternating current signal. The first alternating current signal is detected at the first detection electrode.

摘要: A MEMS switch in which at least first, second and third signal lines are provided over the substrate, which each terminate at a connection region. A lower actuation electrode arrangement is over the substrate. A movable contact electrode is suspended over the connection regions for making or breaking electrical contact between at least two of the three connection regions and an upper actuation electrode provided over the lower actuation electrode. The use of three of more signal lines enables a symmetrical actuation force to be achieved or enables multiple switch functions to be implemented by the single movable electrode, or both.

摘要: A microphone comprises a substrate (20), a microphone membrane (10) defining an acoustic input surface and a backplate (11) supported with respect to the membrane with a fixed spacing between the backplate (11) and the membrane (10). A microphone periphery area comprises parallel corrugations (24) in the membrane (10) and backplate (11). By using the same corrugated suspension for both the membrane and the backplate, the sensitivity to body noise is optimally suppressed.

摘要: A switching circuit employs switches operating at low on resistance and high off capacitance. In connection with various example embodiments, a switching circuit selectively couples a communication port to one of two or more internal circuits based upon a type of input at the communication port. A sensor circuit senses the type of the input and, based upon the sensed input type, actuates one or more switches in the switching circuit.

摘要: As may be consistent with one or more embodiments discussed herein, an integrated circuit apparatus includes a membrane suspended over a cavity, with the membrane and cavity defining a chamber. The membrane has a plurality of openings therein that pass gas into and out of the chamber. As the membrane is actuated, the volume of the chamber changes to generate a gas pressure inside the chamber that is different than a pressure outside the chamber. A sensor detects a frequency-based characteristic of the membrane responsive to the change in volume, and therein provides an indication of the gas pressure outside the chamber.

摘要: A micro-electromechanical device has a substrate (60), a movable element (15), a pair of electrodes (40) arranged on the substrate and on the movable element to move the movable element, and a controller (50) to supply the electrodes. To move the movable element to an intermediate position one or more pulses are applied during the movement, timed to compensate for under or over damping of the movement. This can reduce a settling delay. It can be applied to tunable RF capacitors. To control a decrease in the gap, a single pulse of a maximum supply level compensates for the inherent slowness of the device and over damping. To compensate for under damping, the pulses have a period corresponding to a resonant frequency, and comprise peaks and troughs above and below the final supply level, such that successive ones of the peaks and troughs are closer to the given supply level.

摘要: The present invention provides a capacitive RF-MEMS device comprising a vertically integrated decoupling capacitor (14). The decoupling capacitor (14) therefore does not take extra area. Furthermore, the RF-MEMS according to the invention needs less interconnects, which also saves space and which reduces the series inductance/resistance in the RF path.
