    • To solve problematic trade-off between a bandwidth and a in-band deviation in an optical signal receiving circuit of a gigabit order that is required to have a wide dynamic range, the optical signal receiving circuit has a current-voltage conversion circuit that receives as an input a current signal outputted from a photoelectric conversion circuit for receiving and converting an optical signal into a current signal and converts it into a voltage signal, and realizes the wide dynamic range by providing the current-voltage conversion circuit with an AGC function and a phase compensation function by MOS transistors and a capacitance. Further, by providing the current-voltage conversion circuit with a second phase compensation function by a MOS transistor and a capacitance, it is made possible for the optical signal receiving circuit to reduce the in-band deviation at the time of minimum gain while securing the bandwidth at the time of maximum gain.
