A low power transponder IC for high performance identification systems

A novel integrated circuit for a battery-less transponder system is presented. Battery-less transponders require contactless transmission of both the information and power between a mobile data carrier and a stationary or handheld reader unit. The operating principle of this system gives a superior performance in reading distance due to separation of the powering and data transmission phases. This paper describes the function of the transponder IC and the circuit design techniques used for the various building blocks.<
