Abstract
A light receiving circuit () includes a light inputting circuit () which converts one-system optical signal to be outputted from an optical transmission path () to an electrical signal and inverts a potential of the electrical signal each time the optical signal is detected, and a buffer circuit () which amplifies the electrical signal converted by the light inputting circuit and outputs the same. According to such configuration, since one-system optical signal may be inputted to the light receiving circuit, a system circuit configuration can be avoided to be complicated.
