摘要： A photodiode structure is based on the use of a double junction sensitive to different wavelength bands based on a magnitude of a reverse bias applied to the photodiode. The monolithic integration of a sensor with double functionality in a single chip allows realization of a low cost ultra-compact sensing element in a single packaging useful in many applications which require simultaneous or spatially synchronized detection of optical photons in different spectral regions.

摘要： An integrated electronic device for detecting the composition of ultraviolet radiation includes a cathode region formed by a semiconductor material with a first type of conductivity. A first anode region and a second anode region are laterally staggered with respect to one another and are set in contact with the cathode region. The cathode region and the first anode region form a first sensor. The cathode region and the second anode region form a second sensor. In a spectral range formed by the UVA band and by the UVB band, the first and second sensors have, respectively, a first spectral responsivity and a second spectral responsivity different from one another.

摘要： An embodiment of a geiger-mode avalanche photodiode includes: a body of semiconductor material, having a first surface and a second surface; a cathode region of a first type of conductivity, which extends within the body; and an anode region of a second type of conductivity, which extends within the cathode region and faces the first surface, the anode and cathode regions defining a junction. The anode region includes at least two subregions, which extend at a distance apart within the cathode region starting from the first surface, and delimit at least one gap housing a portion of the cathode region, the maximum width of the gap and the levels of doping of the two subregions and of the cathode region being such that, by biasing the junction at a breakdown voltage, a first depleted region occupies completely the portion of the cathode region within the gap.

摘要： A MEMS sensor has at least a movable element designed to oscillate at an oscillation frequency, and an integrated measuring system coupled to the movable element to provide a measure of the oscillation frequency. The measuring system has a light source to emit a light beam towards the movable element and a light detector to receive the light beam reflected back from the movable element, including a semiconductor photodiode array. In particular, the light detector is an integrated photomultiplier having an array of single photon avalanche diodes.

摘要： In an embodiment, PhotoPlethysmoGraphy (PPG) signals are processed by detecting peaks and valleys in the PPG signal, segmenting the PPG signal to provide a time series of PPG waveforms located between two subsequent valleys in the PPG signal, applying to the waveforms in the time series pattern recognition with respect to a reference PPG waveform pattern produced based on a mathematical model of the PPG signal by assigning to the waveforms in the time series a recognition score. A resulting PPG signal is produced by retaining the waveforms in the time series having an assigned recognition score reaching a recognition threshold, and discarding the waveforms in the time series having an assigned recognition score failing to reach the recognition threshold.

摘要： An array of Geiger-mode avalanche photodiodes is formed in a die and includes: an internal dielectric structure, arranged on the die; and an external dielectric region arranged on the internal dielectric structure. The external dielectric region is formed by an external material that absorbs radiation having a wavelength that falls in a stop-band with low wavelength and transmits radiation having a wavelength that falls in a pass-band with high wavelength, at least part of the pass-band including wavelengths in the infrared. The internal dielectric structure is formed by one or more internal materials that substantially transmit radiation having a wavelength that falls in the stop-band and in the pass-band and have refractive indices that fall in an interval having an amplitude of 0.4. In the stop-band and in the pass-band the external dielectric region has a refractive index with the real part that falls in the above interval.
