Embodiment Construction
[0025] Further illustrate the present invention below in conjunction with accompanying drawing.
[0026] The CMOS self-calibration light intensity measurement and monitoring integrated circuit of the present invention consists of a light intensity measurement circuit 1, a current-voltage linear conversion circuit 2, a self-calibration / monitoring control switch array 3, an output voltage sampling and holding circuit 4, and a comparison amplifier circuit 5. It consists of 5 circuit modules.
[0027] The light intensity measurement circuit 1 converts the light signal into an electrical signal by using the diode photoelectric effect, the photodiodes D1 and D2 are used to convert the light signal into an electrical signal, and the light intensity has a strong dependence on the output current. The photodiodes D1 and D2 adopt a parallel structure, and the output current of the output terminal 1b of the light intensity measurement circuit is the sum of the currents of D1 and D2, which...
