Abstract
The present invention solves characteristic deterioration caused by peaking and a ground inductance, and provides a transimpedance amplifier capable of achieving a higher gain and a wider band. For this purpose, the transimpedance amplifier is configured to include a feedback circuit having two or more extreme frequencies and having a filter characteristic which is flat with respect to frequencies in a frequency region not more than a smallest extreme frequency among the extreme frequencies, which is flat with respect to frequencies in a frequency region not less than a largest extreme frequency among the extreme frequencies, and which has at least one negative inclination portion with respect to frequencies in a frequency region between the smallest and largest extreme frequencies.
