Abstract: A testing tool includes a clock generation circuit generating a test clock and outputting the test clock via a test clock output pad, data processing circuitry clocked by the test clock, and data output circuitry receiving data output from the data processing circuitry and outputting the data via an input/output (IO) pad, the data output circuitry being clocked by the test clock. The testing tool also includes a programmable delay circuit generating a delayed version of the test clock, and data input circuitry receiving data input via the IO pad, the data input circuitry clocked by the delayed version of the test clock. The delayed version of the test clock is delayed to compensate for delay between transmission of a pulse of the test clock via the test clock output pad to an external computer and receipt of the data input from the external computer via the IO pad.

Abstract: A method for manufacturing a filtering module comprising the steps of: forming a multilayer body comprising a filter layer of semiconductor material and having a thickness of less than 10 μm, a first structural layer coupled to a first side of the filter layer, and a second structural layer coupled to a second side, opposite to the first side, of the filter layer; forming a recess in the first structural layer, which extends throughout its thickness; removing selective portions, exposed through the recess, of the filter layer to form a plurality of openings, which extend throughout the thickness of the filter layer; and completely removing the second structural layer to connect fluidically the first and second sides of the filter layer, thus forming a filtering membrane designed to inhibit passage of contaminating particles.

Abstract: A PMUT device includes a membrane element extending perpendicularly to a first direction and configured to generate and receive ultrasonic waves by oscillating about an equilibrium position. At least two piezoelectric elements are included, with each one located over the membrane element along the first direction and configured to cause the membrane element to oscillate when electric signals are applied to the piezoelectric element, and generate electric signals in response to oscillations of the membrane element. The membrane element has a lobed shape along a plane perpendicular to the first direction, with the lobed shape including at least two lobes. The membrane element includes for each piezoelectric member a corresponding membrane portion including a corresponding lobe, with each piezoelectric member being located over its corresponding membrane portion.

Abstract: A method of operating neural networks such as convolutional neural networks including, e.g., an input layer, an output layer and at least one intermediate layer between the input layer and the output layer, with the network layers including operating circuits performing arithmetic operations on input data to provide output data. The method includes: selecting a set of operating circuits in the network layers, performing arithmetic operations in operating circuits in the selected set of operating circuits by performing Residue Number System or RNS operations on RNS-converted input data by obtaining RNS output data in the Residue Number System, backward converting from the Residue Number System the RNS output data resulting from the RNS operations.

Abstract: A microelectromechanical mirror device includes a supporting frame of semiconductor material and a plate of semiconductor material. The plate is connected to the supporting frame so as to be orientable around at least one rotation axis. A reflective layer is arranged on a first region of the plate. A piezoelectric actuation structure extends on a second region of the plate adjacent to the reflective layer. The piezoelectric actuation structure is configured to apply forces such as to modify a curvature of the plate.

Abstract: An electronic module includes a first die of semiconductor material including a first reflector, a second die of semiconductor material including a second reflector, and a frame including a first supporting portion and a second supporting portion parallel to one another. The first and second dies are carried, respectively, by the first and second supporting portions and are respectively arranged so that the first reflector faces the second supporting portion and the second reflector faces the first supporting portion. An incoming light beam impinges upon the first reflector and is reflected on the second reflector so as to be supplied at output from the electronic module.

Abstract: A delta-sigma modulation circuit has a sampling period and, in operation, generates a delta-sigma modulated signal based on the analog input signal. The delta-sigma modulation circuit includes: a first integrator; an analog-to-digital converter; a feedback-loop coupled between an input of the first integrator and the output interface; a second integrator coupled between the first integrator and the analog-to-digital converter. The delta-sigma modulation circuit has loop-delay compensation circuitry having a plurality of switches. The loop delay compensation circuitry, in operation, controls the plurality of switches based on a time interval of a duration of half the sampling period and generates a loop-delay compensation signal.

Abstract: A structural body made of semiconductor material includes an active area housing a drain region, a body region and a source region within the body region. An electrical-isolation trench extends in the structural body to surround the active area.
