Claim 4:
5. A switching method, comprising:
electrically coupling a switching circuit to a first impedance circuit, a second impedance circuit, a positive terminal of a frequency generation circuit and a negative terminal of the frequency generation circuit;
adjusting an impedance value of the second impedance circuit according to a first clock signal and a second clock signal outputted by the frequency generation circuit;
periodically conducting the negative terminal to one of the first impedance circuit and the second impedance circuit by a first switching unit of the switching circuit, wherein the first switching unit is electrically coupled to the first impedance circuit through a first impedance node, and is electrically coupled to the second impedance circuit through a second impedance node; and
periodically conducting the positive terminal to the other one of the first impedance circuit and the second impedance circuit by a second switching unit of the switching circuit, wherein the second switching unit is electrically coupled to the first impedance circuit through the first impedance node, and is electrically coupled to the second impedance circuit through the second impedance node, wherein the first impedance node and the second impedance node are electrically isolated in a switching operation of the switching circuit.
