1. A signal transmission circuit comprising:

  • a first driving circuit, comprisinga first differential output pair, comprising a positive end and a negative end, electrically connected to a first external resistor; and

    a plurality of input/output units, electrically between a first node and a second node, for receiving a positive control signal and a negative control signal, and generating a first superimposed current at the first differential output pair; and

    a calibration module, electrically connected to the first driving circuit, for transmitting a calibration signal to the first driving circuit, for setting whether the input/output units in the first driving circuit are in operation, and generating the first superimposed current flowing to the first external resistor according to the positive control signal and the negative control signal.
