Burst trans-impedance amplifier with reset signal

The invention provides a burst trans-impedance amplifier with a reset signal. An input photocurrent signal is input from a junction of an input end of a forward amplifier-A and a feedback resistor RF.An NMOS tube NO is connected with the feedback resistor RF in parallel; an output signal of the forward amplifier-A is divided into two paths, and one path is directly input into the inverting inputend of the differential voltage amplifier Diff Amp; the other path passes through resistors RS and RL in series and then is input to a differential voltage amplifier Diff Amp and an inverting input end of an operational amplifier OP; after being amplified by the differential voltage amplifier, the signal is converted into a differential signal OUTP/OUTN, and the differential signal OUTP/OUTN is output to the outside of the chip; and a switch S is connected with the resistor RL in parallel and is controlled by the reset signal RESET. In the lead code stage, the switch s is switched on, and in the data section, the switc
