The present disclosure provides a pulse filtering circuit with two input ports and two output ports, including: a first signal path with a first buffer unit, a first comparison unit, and a first shaping unit; and a second signal path with a second buffer unit, a second comparison unit, and a second shaping unit; each of the first comparison unit and the second comparison unit has four ports, which are a first port, a second port, a third port and a fourth port; the first port of each comparison unit serves as an input control port, the second port of each comparison unit serves as an output port, the third port serves as a fixed potential port, and the fourth port serves as a floating potential input port. The new pulse filtering circuit of the present disclosure may eliminate the common-mode noise signal, especially the dV/dt common-mode noise generated by the power supply, and therefore the circuit has a strong anti-dV/dt noise capability and a small transmission delay, and at the same time reduces the chip area and production costs due to its simple circuit structure.
