【Abstract】 Anti-collision is necessary for the system of contactless IC card. To increase the anti-collision speed and reduce the circuit power dissipation, a new algorithm based on the dynamic binary is presented FPGA is used to verify the function of the circuit designed. Meanwhile, power dissipation simulation for the anti-collision circuit shows good performance.更多还原
