Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a photoelectric detector circuit. Background technique [0002] Photodetector refers to a physical phenomenon in which the conductivity of the irradiated material is changed by radiation. Photodetectors are widely used in various fields of military and national economy. In optical application systems, photodetectors are often used to detect ambient light to convert optical signals into electrical signals. For photodetectors, sensitivity, bandwidth, and dynamic range are key operating parameters that are typically used to define the performance of the photodetector. The optical signal is converted into an electrical signal representing ambient light, which can be further processed by other circuits to meet the needs of various applications. The photodetector circuit in the prior art is complex, difficult to manufacture, high in cost, and the detection accuracy is not hi...
