Abstract
There is disclosed a photo-electronic integrated circuit device comprising a first and second output terminals for supplying first and second output signal of opposite polarities to an external differential input logic circuit, a photo-detecting device for converting an input light signal to an electrical signal, a first amplifier for amplifying the electrical signal of the photo-detecting device and outputting the same from the first output terminal as the first output signal, and a second amplifier for amplifying the output of the first amplifier and outputting the second output signal having the opposite phase to that of the first output signal, from the second output terminal.
