摘要： A differential circuit system is provided. The differential circuit system includes: a different circuit set including a plurality of differential circuits, a voltage regulator, and a current drainage circuit set. The differential circuits are electrically connected between a first node and a second node, and each differential circuit generates a current flowing from the first node to the second node. A high voltage is provided to the first node and a low voltage is provided to the second node. The first node receives an external voltage. According to the first voltage, the voltage regulator generates the low voltage. The low voltage is provided to the second node. The current drainage circuit set generates a drainage current in between the second node and a ground voltage. A superposed current flowing to the voltage regulator is difference of the summation of currents minus the conducting current.

摘要： A receiver circuit including an external terminal, a level shifter, a reset circuit, and an inverting circuit is provided. The external terminal receives the external signal. The level shifter shifts a voltage swing range of the external signal to generate a level shifting signal. The level shifter includes a pull-up unit and a pull-down unit coupled in series. The pull-up unit and the pull-down unit are alternatively switched respectively according to the external signal and the internal signal, and thus a leakage path of the level shifter is cut off for different states of the external signal. The reset circuit couples the external terminal and the level shifter and provides a reset path according to the external signal for assisting the switching of the pull-up unit and the pull-down unit. The inverting circuit couples the level shifter and inverts the level shifting signal to generate the internal signal.

摘要： A signal transmission circuit is provided. The signal transmission circuit includes a first driving circuit including a first differential output pair, a plurality of input/output units and a calibration module. The first differential output pair includes a positive and a negative ends. The plurality of input/output units receive a positive and a negative control signals and generate a first superimposed current at the first differential output pair. The calibration module transmits a calibration signal to the first driving circuit. The calibration module sets operation of each of the input/output unit in the first driving circuit, and generates the first superimposed current flowing to a first external resistor according to the positive and the negative control signals.
