Abstract: A micro-electro-mechanical device formed in a monolithic body of semiconductor material accommodating a first buried cavity; a sensitive region above the first buried cavity; and a second buried cavity extending in the sensitive region. A decoupling trench extends from a first face of the monolithic body as far as the first buried cavity and laterally surrounds the second buried cavity. The decoupling trench separates the sensitive region from a peripheral portion of the monolithic body.

Abstract: An electrostatically actuated oscillating structure includes a first stator subregion, a second stator subregion, a first rotor subregion and a second rotor subregion. Torsional elastic elements mounted to the first and second rotor subregions define an axis of rotation. A mobile element is coupled to the torsional elastic elements. The stator subregions are electrostatically coupled to respective regions of actuation on the mobile element. The stator subregions exhibit an element of structural asymmetry such that the electrostatic coupling surface between the first stator subregion and the first actuation region differs from the electrostatic coupling surface between the second stator subregion and the second actuation region.

Abstract: An integrated MEMS structure includes a driving assembly anchored to a substrate and actuated with a driving movement. A pair of sensing masses suspended above the substrate and coupled to the driving assembly via elastic elements is fixed in the driving movement and performs a movement along a first direction of detection, in response to an external stress. A coupling assembly couples the pair of sensing masses mechanically to couple the vibration modes. The coupling assembly is formed by a rigid element, which connects the sensing masses and has a point of constraint in an intermediate position between the sensing masses, and elastic coupling elements for coupling the rigid element to the sensing masses to present a first stiffness to a movement in phase-opposition and a second stiffness, greater than the first, to a movement in phase, of the sensing masses along the direction of detection.

Abstract: An electronic circuit drives a plurality of LED strings connected in series. The electronic circuit includes a regulation module corresponding to each LED string, with the regulation module connected to the cathode terminal of the corresponding LED string. Each regulation module is further coupled to receive a reference voltage in phase with a rectified a.c. voltage. The regulation modules execute in turn and in sequence a current-regulation phase as a function of a trend of the reference voltage. Each regulation module, when executing the current-regulation phase, functions to regulate the current that flows in the corresponding LED string and in any previous LED strings in the series connection so that the regulated current is proportional to the reference voltage.

Abstract: A bi-synchronous electronic device may include a FIFO memory circuit configured to store data, and a first digital circuit coupled to the FIFO memory circuit and configured to operate based upon a first clock signal and a write pointer, write a data burst to the FIFO memory circuit, thereby causing a jump in the write pointer to a new position, and write a burst indicator associated with the new position in the FIFO memory circuit. The bi-synchronous electronic device may include a second digital circuit coupled to the FIFO memory circuit and configured to operate based upon a second clock signal different from the first clock signal, read from the FIFO memory circuit based upon a read pointer, and synchronize the read pointer to the write pointer based upon the burst indicator.

Abstract: An active high gain filter includes high value resistances in feedback implemented using a negative resistance circuit configuration. The high value resistance is implemented using two or smaller resistances connected in the negative resistance circuit configuration. This implementation permits integration of the filter circuit using less occupied area while still providing an accurate transfer function response.

Abstract: In one embodiment, a semiconductor device includes one or more metallizations, such as, e.g., Cu-RDL metallizations, provided on a passivation layer over a dielectric layer. A via is provided through the passivation layer and the dielectric layer in the vicinity of the corners of the metallization. The via may be a “dummy” via without electrical connections to an active device and may be provided at a distance between approximately 1 micron (10−6 m.) and approximately 10 micron (10−5 m.) from each one of said converging sides landing on an underlying metal layer.
