A control device includes a first terminal receiving a monitored output voltage and a second terminal transmitting a pulse width modulation (PWM) signal. A converting unit generates an A/D conversion synchronous signal, and an A/D converter samples the monitored output voltage in accordance with the A/D conversion synchronous signal. A pulse oscillator controls a position of a first edge on the PWM signal in accordance with the A/D conversion synchronous signal, and controls a position of a second edge based on the monitored voltage.

A power supply controller includes an analog to digital (A/D) converter that performs analog-digital conversion of an output voltage and outputs a digital signal, a deviation signal generator unit that generates a deviation signal from the digital signal and a standard voltage value serving as an output voltage target value, and a power controller unit that controls the output voltage based on the deviation signal. The power supply controller includes a conversion range setting unit that sets a range of the reference voltage into the A/D converter based on a first signal as the digital signal in a power supply startup period, and sets the reference voltage range into the A/D converter based on a second signal as the deviation signal or as a signal corresponding to the deviation signal in a steady state period.

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.
