ABSTRACT:
An optical receiving circuit comprising a plurality of amplifying circuits successively connected in a multiple stage form, each of the plurality of amplifying circuits having an offset compensating function. The optical receiving circuit includes offset compensating circuits respectively arranged in the plurality of amplifying circuits. Time constants of the offset compensating circuits are set in such a manner that the time constant of an offset compensating circuit arranged at one stage is smaller than that of an offset compensating circuit arranged at the previous stage.
