Abstract: A MEMS actuator includes a monolithic body of semiconductor material, with a supporting portion of semiconductor material, orientable with respect to a first and second rotation axes, transverse to each other. A first frame of semiconductor material is coupled to the supporting portion through first deformable elements configured to control a rotation of the supporting portion about the first rotation axis. A second frame of semiconductor material is coupled to the first frame by second deformable elements, which are coupled between the first and the second frames and configured to control a rotation of the supporting portion about the second rotation axis. The first and second deformable elements carry respective piezoelectric actuation elements.

Abstract: An integrated circuit includes a die that includes a circuit configured to generate a PWM signal in response to a first clock signal, and a first set of pads configured to provide amplified PWM signals to external filters. An amplifier stage is configured to provide the amplified PWM signals. The die includes two pads configured to be coupled to an external inductor, and a second set of pads configured to provide regulated voltages. An electronic converter circuit is configured to generate the regulated voltages to supply the amplifier stage. The electronic converter circuit includes a control circuit configured to drive electronic switches in response to a second clock signal to regulate the regulated voltages to a respective target value. The die includes a control block to synchronize the switching activity of the electronic switches with the switching activity of the amplifier stage.

Abstract: A circuit includes a capacitance coupled between a high voltage node and ground, a laser diode having an anode coupled to the high voltage node and a cathode coupled to an output node, and a current source coupled between the output node and ground. The current source turns on based on assertion of a trigger signal and sinks current from the capacitance to ground to thereby cause the laser diode to lase, and turns off based on deassertion of the trigger signal. A clamping circuit is coupled between the output node and the high voltage node, and clamps voltage at the output node occurring when the current source switches off.

Abstract: A light-emitting device may include a semiconductor body having a first conductivity type, with a front side and a back side. The light-emitting device may also include a porous-silicon region which extends in the semiconductor body at the front side, and a cathode region in direct lateral contact with the porous-silicon region. The light-emitting device may further include a barrier region of electrically insulating material, which extends in direct contact with the cathode region at the bottom side of the cathode region so that, in use, an electric current flows in the semiconductor body through lateral portions of the cathode region.

Abstract: In some embodiments, a processing system includes at least one hardware block configured to change operation as a function of configuration data, a non-volatile memory including the configuration data for the at least one hardware block, and a configuration module configured to read the configuration data from the non-volatile memory and provide the configuration data read from the non-volatile memory to the at least one hardware block. The configuration module is configured to: receive mode configuration data; read the configuration data from the non-volatile memory; test whether the configuration data contain errors by verifying whether the configuration data are corrupted and/or invalid; and activate a normal operation mode or an error operation mode based on whether the configuration data contain or do not contain errors.

Abstract: A method of controlling synchronous rectification transistors in a switching converter includes sensing a drain-to-source voltage across each synchronous rectification transistor each switching half-cycle of the switching converter. An average of the sensed drain-to-source voltage is calculated for each synchronous rectification transistor over N prior switching half-cycles. A load current transient in the switching converter is sensed based on the sensed drain-to-source voltage of each synchronous rectification transistor and the calculated average of the sensed drain-to-source voltage for each synchronous rectification transistor over the N prior switching half-cycles.

Abstract: A method of sensing a temperature includes providing a voltage to reverse bias a PN junction of a junction diode. The PN junction has a junction capacitance. The method includes providing a reverse bias voltage change across the PN junction and detecting a value of the junction capacitance in response to the reverse bias voltage change. The value of the junction capacitance is a function of a temperature of the PN junction. An output signal is generated based on the detected junction capacitance, where the output signal indicates a temperature of an environment containing the junction diode.

Abstract: A touchscreen resistive sensor includes a network of resistive sensor branches coupled to a number of sensor nodes arranged at touch locations of the touchscreen. A test sequence is performed by sequentially applying to each sensor node a reference voltage level, jointly coupling to a common line the other nodes, sensing a voltage value at the common line, and declaring a short circuit condition as a result of the voltage value sensed at the common line reaching a short circuit threshold. A current value level flowing at the sensor node to which the reference voltage level is applied is sensed and a malfunction of the resistive sensor branch coupled with the sensor node to which a reference voltage level is applied is generated as a result of the current value sensed at the sensor node reaching an upper threshold or lower threshold.
