Abstract: 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.

Abstract: An electronic circuit includes a substrate. A capacitor and at least one semiconductor component are supported by a surface of the substrate. A substantially planar screen, oriented parallel to the surface of the substrate and made of metallic material, is placed between the capacitor and the semiconductor component. Preferably, the semiconductor component is placed in proximity to the surface of the substrate and several superposed layers of insulating material cover the surface of the substrate and the semiconductor component. The capacitor is then placed within at least one layer of insulating material above the semiconductor component, and the screen is placed within an intermediate layer of insulating material between the layer incorporating the capacitor and the surface of the substrate.

Abstract: The component has a bulk acoustic wave resonator with a resonance frequency and an anti-resonance frequency. An inductor cancels the anti-resonance frequency of the resonator and has one Q-factor in a predetermined frequency range and another value of Q outside the frequency range. A capacitor adjusts the tuning of the resonator on the resonance frequency.

Abstract: The transistor (32) has doped areas corresponding to two main terminals of elementary MOS transistors, and including a shape of parallel strips separated by gate regions. Two set of conductive elements (54, 56 and 58, 60) are not partially extended on the doped areas corresponding to one of two main terminals. The conductive elements are divided into two set of fingers that are partially extended on the doped areas corresponding to another main terminals, respectively, where one set of fingers are partially intercalated with another set of fingers.

Abstract: The method involves generating a filtered sampled signal (SF) according to a redundant arithmetic coding e.g. borrow-save coding. An output signal (Y) sampled on n bits is generated by using non-exact quantization. The generation of the output signal is anticipated, where the generation of the output signal is parallely carried out at the final elementary processing of the generation of the filtered sampled signal. An independent claim is also included for a digital delta-sigma modulator comprising a digital filtering unit.
