    Abstract: An integrated capacitive-type humidity sensor formed in a semiconductor chip integrating a sensing capacitor and a reference capacitor. Each of the sensing and reference capacitors have at least a first electrode and at least a second electrode, the first and second electrodes of each of the sensing and reference capacitors being arranged at distance and mutually insulated. A hygroscopic layer extends on the sensing and reference capacitors and a conductive shielding region extends on the reference capacitor but not on the sensing capacitor.

    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.

    Abstract: Radiation sensor including a detection assembly and a chopper assembly, which are mechanically coupled to delimit a main cavity; and wherein the chopper assembly includes: a suspended movable structure, which extends in the main cavity; and an actuation structure, which is electrically controllable to cause a change of position of the suspended movable structure. The detection unit includes a detection structure, which faces the main cavity and includes a number of detection devices. The suspended movable structure includes a first shield of conductive material, which shields the detection devices from the radiation, the shielding of the detection devices being a function of the position of the suspended movable structure.

    Abstract: An electronic amplification-interface circuit includes a differential-current reading circuit having a first input terminal and a second input terminal. The differential-current reading circuit includes a continuous-time sigma-delta conversion circuit formed by an integrator-and-adder module generating an output signal that is coupled to an input of a multilevel-quantizer circuit configured to output a multilevel quantized signal. The integrator-and-adder module includes a differential current-integrator circuit configured to output a voltage proportional to an integral of a difference between currents received at the first and second input terminals. A digital-to-analog converter, driven by a respective reference current, receives and converts the multilevel quantized signal into a differential analog feedback signal. The integrator-and-adder module adds the differential analog feedback signal to the differential signal formed at the first and second input terminals.
