Abstract: The present embodiments provide an analog to digital converter, including a beam splitter, M photodetectors, M amplifier modules, and an encoder. Each output end of the beam splitter is corresponding to an input end of a photodetector, an output end of each photodetector is connected to an input end of an amplifier module, and an output end of each amplifier module is connected to an input end of the encoder. The beam splitter splits an inputted analog optical signal into M optical signals, outputs each optical signal to a corresponding photodetector to convert each optical signal into a current signal, inputs each current signal to a corresponding amplifier module to generate an output voltage, and outputs the output voltage to a corresponding input end of the encoder.
