Abstract:
An integrated electronic device for detecting the composition of ultraviolet radiation, including: a cathode region (6, 8) formed by a semiconductor material with a first type of conductivity; and a first anode region (10; 410; 510) and a second anode region (12; 412; 512), which 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 (32). The cathode region and the second anode region form a second sensor (34). 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.
