    摘要： A switching circuit employs MEMS devices. In connection with various example embodiments, signal switching circuit couples primary and secondary data link connectors having at least two channels and an electrode for each channel. A MEMS switch is coupled to each channel in of the secondary data link connectors, and includes a suspended membrane, first and second contact electrodes (one being in the membrane) and a biasing circuit that biases the membrane for moving the membrane between open and closed positions to contact the electrodes. A switch controller circuit selectively controls the application of an actuation voltage to each of the biasing circuits, thereby selectively actuating the membranes between the open and closed positions for routing signals between the primary and secondary data link connectors.

    摘要： The invention relates to electronic device having an operation temperature range, wherein the electronic device comprises a tunable capacitor (CST) comprising a first electrode (BE), a second electrode (TE), and a dielectric (FEL) arranged between the first electrode (BE) and the second electrode (TE). The dielectric (FEL) comprises dielectric material (FEL) having a value of a relative dielectric constant (εr) varying at least within the operation temperature range. The electronic device further comprises a temperature varying means (RES) being thermally coupled to the tunable capacitor for providing a temperature of the dielectric (FEL) causing a predetermined capacitance of the tunable capacitor (CST). The invention, which relies on the idea of varying temperature to vary a capacitance of a capacitor stack, provides an alternative tunable capacitor type for the known types. Advantageous embodiments feature high-tuning ratio, small device area, and stable capacitance value in case the temperature is well controlled. The invention further relates to a semiconductor device comprising the electronic device in accordance with the invention, to an electronic circuit comprising such electronic device, and to a method of manufacturing such electronic device.

    摘要： A MEMS tunable capacitor comprises first and second opposing capacitor electrodes, wherein the second capacitor electrode is movable by a MEMS switch to vary the capacitor dielectric spacing, and thereby tune the capacitance. A tunable dielectric material and a non-tunable dielectric material are in series between the first and second electrodes. The tunable dielectric material occupies a dimension gd of the electrode spacing, and the non-tunable dielectric material occupies a dimension g of the electrode spacing. A third electrode faces the movable second electrode for electrically controlling tunable dielectric material. A controller is adapted to vary the capacitor dielectric spacing for a first continuous range of adjustment of the capacitance of the MEMS capacitor, and to tune the dielectric material for a second continuous range of adjustment of the capacitance of the MEMS capacitor, thereby to provide a continuous analogue range of adjustment including the first and second ranges. This arrangement provides independent control of the MEMS function and the dielectric tuning function, and enables a continuous adjustability.
