Radiation-detection device with improved illumination range |
摘要 |
The device has a control circuit (3) for converting current issued by a photodetector (1) into an electrical variable. A switch (9) connects the photodetector to an output terminal (8) of a pixel, and is arranged to be in a blocking state when the photodetector is in an operating mode and to be in a passing state when the photodetector is in another operating mode. A comparator (10) compares terminal voltages of a capacitive load (5) relative to a threshold value and delivers a signal according to the comparison, and is connected to a pair of switches (6, 7) and the switch. |
