摘要： Disclosed are a method and a circuit for impedance matching. The method comprises: a peripheral impedance detection module detecting an impedance of a subscriber telephone and outputting information about the impedance of the subscriber telephone; an analog switch switching module providing an impedance matching path between the impedance of the subscriber telephone and an impedance matching module according to the information about the impedance of the subscriber telephone output by the peripheral impedance detection module; the impedance matching module providing a corresponding impedance through the impedance matching path provided by the analog switch switching module to match to said impedance of the subscriber telephone. By the present invention, the impedance matching is achieved when a wireless access box communicates with telephones with various impedance modes. The matching process is flexible, automatic, and does not need manual configuration, and the technology is simple, reliable, and of low cost.
