Abstract:
Provided is a photodetection device which is small in size and has excellent sensitivity. A photodetection device puts cathode terminals of photodiodes having different spectral characteristics into an open end state, and detects light intensity of a desired wavelength region according to a difference in electric charges that have been stored in those photodiodes in a given period of time. The photodiodes employ a system of storing electric charges, and hence even if a photocurrent is small, the photocurrent may be stored to obtain the electric charges required for detection, and the downsizing and high detection performance of a semiconductor device that forms the photodiodes may be achieved. Further, a wide dynamic range may be realized with an electric charge storage time being variable according to the light intensity, to intermittently drive an element required for difference detection at the time of difference detection so as to suppress electric power consumption, or to average the output so as to reduce flicker.
Abstract:
Provided is an illuminance sensor in which a consumption current is independent of an illuminance level of incident light. Amplifiers (21 to 24) and a subtraction circuit (25) are driven by a constant current source (not shown). The subtraction circuit (25) outputs a differential voltage between output voltages of a photodetector element (15) and a photodetector element (16). Based on the differential voltage, a sample/hold circuit (30) performs sampling or holding of a voltage at one end of a capacitor (13). A switch (28) is ON when an output voltage of the subtraction circuit (25) starts to change, thereby fixing the voltage at the one end of the capacitor (13) to a reference voltage.
