Optoelektronische integrierte Schaltung

摘要

There is disclosed an optoelectronic integrated circuit comprising a plurality of channels each including an optical receiving device (PD1; ... PDn) for converting a received optical signal to an electric signal, and an amplifier (AMP1; ... AMPn) for amplifying an output signal of the optical receiving device, the channels being integrated on the same semiconductor substrate, electric power source nodes of at least two of the amplifiers of the respective channels being connected to a common electric power source node (11), and the common electric power source node (11) being connected through a resistor element (R) to an electric source power supply terminal (12) for supplying an electric source power to the channels.
