Abstract :
This paper have elaborated the technology and application of RFID briefly, and analyzed zero intermediate-frequency receiver´s theory and several inevitable key questions when used in the system. For example, the receive scotoma which produces by the label position change, signal direct-current displacement and so on. The paper proposes the solution and has carried on the actual electric circuit´s test and the confirmation.
