Abstract
According to one embodiment, a receiving circuit is provided. The receiving circuit has a first light receiving element, a signal voltage generator, a second light receiving element, a delay element and a comparator. The first light receiving element receives a light signal and converts the light signal into a first current. The signal voltage generator converts the first current into a signal voltage. The second light receiving element receives the light signal and converts the light signal into a second current. The reference voltage generator converts the second current into a voltage and outputs the voltage as a reference voltage. The delay element delays and reduces a signal component of the reference voltage. The comparator compares the signal voltage from the signal voltage generator with a threshold voltage based on an output voltage of the delay element.
