| Abstract: | In order to meet the market demand of improving the reading and writing efficiency of reader,a kind of RFID reader design plan based on ISO18000-6C protocol is presented.Digital baseband circuit includes ARM and FPGA.Due to the advantage of FPGA in fast encoding and decoding,and the advantage of ARM in controlling,the reader has characterristic of high recognition and recognize effectively.In circuit design of RF circuit,two amplifiers are used in order to reduce noise effectively,gain well linearity,win high radiant power and recognize tags at a distance.The receiving circuit includes four ways of demodulation,so that the "fuzzy point" can be solved. |
