Abstract: <P>PROBLEM TO BE SOLVED: To provide a transimpedance amplifier in which signal distortion is reduced when converting and amplifying an optic-electric converted current signal into a voltage signal.  <P>SOLUTION: In the transimpedance amplifier core 210, an input current from a light receiving element 10 is inputted as an impedance-converted and amplified single-phase voltage signal to a forward-phase input terminal side of a single-phase/differential conversion circuit 220 via an interface circuit 230. On the other hand, a reference voltage from a reference circuit 240 in which an output impedance is set to the same value as that of the transimpedance amplifier core 210, is inputted to a backward-phase input terminal side of the single-phase/differential conversion circuit 220 via the interface circuit 230. Thus, forward-phase and backward-phase differential voltage signals are outputted. The reference circuit 240 is formed in the same circuit configuration as the transimpedance amplifier core 210, an input terminal is brought into an open state, and a filter circuit 241 is provided which attenuates a high-frequency component outputted from the reference circuit 240.  <P>COPYRIGHT: (C)2009,JPO&INPIT
