摘要： A bulk acoustic wave resonator has an adjustable resonance frequency. A piezoelectric element is provided having first and second electrodes. A switching element is provided in the form of a MEMS structure which is deformable between a first and second position. The switching element forms an additional electrode that is selectively disposed on top of, and in contact with, one of the first and second electrodes. This causes a total thickness of the electrode of the resonator to be changed resulting in a modification of the resonance frequency of the resonator.

摘要： An electronic circuit includes several (at least two) oscillating and/or resonant devices. The circuit uses a measuring device to measure the phase noise of one of the two oscillating/resonant devices. This measuring device is integrated on a chip on which the oscillating/resonant device to be measured is also integrated. The circuits and methods described find application in the area of radiofrequency/high frequency electronics RF/HF, in particular adapted to general public applications in mobile communication systems and/or to metrology.

摘要： A filtering circuit based on a lattice structure comprising a first and a second input and a first and second output. The circuit further comprises two series impedance and two parallel impedance which each comprises an acoustic resonator associated with two inductive and capacitive components which can be adjusted by a first control value. The second and fourth impedance comprise each an acoustic resonator associated to two inductive and capacitive components which are adjustable by means of a second control value. A control circuit generates the two control values which simultaneously comprise a common mode potential and a differential mode potential which allows the emergence of first and second pass bands which are usable for realizing two different bandpass filters.

摘要： An electronic circuit comprises a substrate (100), a capacitor (11) and at least one semiconductor component (10) which are supported by a surface (S) of the substrate. A substantially plane screen (12), parallel to the surface of the substrate and made of metallic material, is furthermore placed between the capacitor and the semiconductor component. Preferably, the semiconductor component is placed in proximity to the surface (S) of the substrate and several superposed layers (1-6) of insulating material cover the surface of the substrate and the semiconductor component. The capacitor is then placed within at least one layer (5) of insulating material above the semiconductor component, and the screen (12) is placed within an intermediate layer (4) of insulating material between the layer incorporating the capacitor and the surface (S) of the substrate.
