发明名称 Light receiving amplifier circuit and optical pickup device having the same
摘要 In a light receiving amplifier circuit, a dummy amplifier has an identical structure with an IV amplifier except that the dummy amplifier is not connected to a light receiving element and includes a capacitor, i.e., a band limiting capacitor. Further, the capacitor is connected between the collector of the grounded-emitter transistor Tr and GND.
