Burst mode trans-impedance amplifier

A burst mode trans-impedance amplifier, comprising:

• a voltage input circuit, sensing an optical signal and converting the optical signal into an input voltage signal;
• a differential circuit, having two input ends and an output end, wherein one input end is coupled to the voltage input circuit and is used for receiving the input voltage signal, the other input end is coupled to a threshold voltage signal, and the output end is used for regulating and outputting a differential voltage signal according to the input voltage signal and the threshold voltage signal;
• and
• a feedback regulation circuit, having an input end and an output end, the input end being coupled to the output end of the differential circuit and used for receiving the differential voltage signal, the output end being coupled to the voltage input circuit and used for outputting a voltage regulation signal to the voltage input circuit according to the differential voltage signal.
