The invention proposes a method and circuit for confirming the correctness of signals, and a charging system using the circuit. The method for confirming the correctness of the signal includes: providing a current through a time-dependent impedance circuit. The impedance of the time-dependent impedance circuit changes with time. At the first time point, the current passes through the time-dependent impedance circuit to generate a second A voltage, and at a second time point, the current passes through the time-varying impedance circuit to generate a second voltage, wherein the first voltage is different from the second voltage. If the relationship between the first voltage and the second voltage conforms to the default relationship, it is confirmed that the signal provided by the node coupled with the time-varying impedance circuit is correct.
