Abstract:
An optical receiver circuit is configured as follows: a preamplifier and a reference voltage generating circuit are connected with a first ground potential wiring and a first power supply wiring, which are used in common, and are formed in a first region where elements are formed on a substrate to which the potential of the first ground potential wiring is supplied; a main amplifier is connected with a second ground potential wiring and a second power supply wiring, which are separated from the first ground potential wiring and the first power supply wiring, and is formed in a second region where elements are formed on the substrate to which the potential of the second ground potential wiring is supplied; and a substrate supply interval where a first substrate supply position at which the potential of the first ground potential wiring is supplied and a second substrate supply position at which the potential of the second ground potential wiring is supplied are closest to each other is large to an extent where a substrate permeability characteristic, in which noise is fully attenuated in an alternating current (AC) manner, is obtained.
