Abstract: A semiconductor device includes a leadframe that includes contact pins and a semiconductor die that has protruding connection formations. A flexible support member is disposed between the leadframe and the semiconductor die and supports the semiconductor die. The flexible support member has electrically conductive lines that extend between the leadframe and the semiconductor die. The electrically conductive lines of the flexible support member are electrically coupled with the contact pins of the leadframe and with the connection formations of the semiconductor die.

The circuit includes a string of capacitors coupled to a circuit input to receive energy to be harvested. A string of transistors are coupled as pumping transistors to respective ones of the capacitors in the string of capacitors. A compensation coupling circuit is coupled between each transistor in the string of pumping transistors and one of a subsequent or a preceding transistor in the string of pumping transistors.

Abstract: A communication interface couples a transmission circuit with an interconnection network. The transmission circuit requests transmission of a predetermined amount of data. The communication interface receives data segments from the transmission circuit, stores the data segments in a memory, and verifies whether the memory contains the predetermined amount of data. When the memory contains the predetermined amount of data, the communication interface starts transmission of the data stored in the memory. Alternatively, when the memory contains an amount of data less than the predetermined amount of data, the communication interface determines a parameter that identifies the time that has elapsed since the transmission request or the first datum was received from the aforesaid transmission circuit, and verifies whether the time elapsed exceeds a time threshold. In the case where the time elapsed exceeds the time threshold, the communication interface starts transmission of the data stored in the memory.

Abstract: A phase shifter, which carries out a ninety-degree phase shift of a sinusoidal input signal having an input frequency, at the same input frequency, envisages: a continuous-time all-pass filter stage, which receives the sinusoidal input signal and generates an output signal phase-shifted by 90° at a phase-shift frequency that is a function of a RC time constant of the all-pass filter stage; and a calibration stage, which is coupled to the all-pass filter stage and generates a calibration signal for the all-pass filter stage, such that the phase-shift frequency is equal to the input frequency of the sinusoidal input signal, irrespective of variations of the value of the input frequency and/or of the RC time constant with respect to a nominal value.

Abstract: A process for manufacturing a surface-mount electronic device includes forming a plurality of preliminary contact regions of a sinterable material on a supporting structure, the supporting structure being of a soluble type. A chip including a semiconductor body is mechanically coupled to the supporting structure. The sinterable material is sintered such that each preliminary contact region forms a corresponding sintered preliminary contact, and the chip and the plurality of preliminary contact regions are coated with a dielectric coating region, and the supporting structure is removed using a jet of liquid.

Abstract: A device includes an interface and Time Division Multiple Access (TDMA) Medium Access Control (MAC) circuitry coupled to the interface. The TDMA MAC circuitry detects a beacon in a frame having a defined frame duration and determines a frame compensation value based on a start time of the frame, a reference start time of the frame, and a number of elapsed frames. A current frame duration value is determined based on the frame compensation value and the defined frame duration.

Abstract: A MEMS actuator device of a piezoelectric type formed on a substrate, with a base unit including a base beam element having a main extension in a extension plane and a thickness in a thickness direction perpendicular to the extension plane, smaller than the main extension. A piezoelectric region extends over the beam element. An anchor region is rigid to the base beam element and to the substrate. A base constraint structure is connected to one end of the base beam element and is configured to allow a deformation of the base beam element in the extension plane and substantially reduce a deformation of the base beam element in the thickness direction.

Abstract: A system for detecting objects, for driver assistance equipment in motor vehicles for example, includes a transmitter for transmitting towards an object an optical signal having a signal energy. The optical signal transmitted includes at least one encoded pulse sequence with the signal energy distributed over the pulse sequence. A receiver receives an echo signal resulting from reflection of the optical signal at the object with the time delay of the echo signal is indicative of the distance to the object.
