摘要： An amplifier unit is provided, with which the need for manufacturing a photoelectric conversion IC in Bi-CMOS process is eliminated, and relatively low process cost of the photoelectric conversion IC is achieved. The input section of a buffer (the base of a transistor Q5) is connected with a plurality of patterns of phase compensation circuits each including a resistor and a capacitor connected in series. A bipolar transistor (Q6) is interposed between a positive power supply line and a capacitor (C2) forming a capacitance of the phase compensation circuit. By switching on/off the bipolar transistor (Q6), the capacitance value and resistance value of the phase compensation circuit are switched. Since the bipolar transistor (Q6) is interposed between the capacitor (C2) and the positive power supply line, base current (Isw) acting as a switch signal does not affect the amplifier unit.
