Abstract
A light receiving circuit includes first, second, and third resistors, a photodiode that is connected in series with the first resistor between first and second potential lines, and a first MOS transistor of a first conductivity type having a source connected to a second node, a drain connected to an output, and a gate connected to a first node that is between the first resistor and the photodiode. The light receiving circuit also includes a capacitor which is connected in parallel to the second resistor between the first potential line and the second node. The third resistor is connected between the output and the second potential line.
