Low power digital circuits for a RFID tag

摘要

The present invention relates to a low-power digital circuit structure of a passive RFID tag . In the present invention, a digital circuit portion of the passive RFID tag , receives instructions from the instruction execution and the analysis , and of which the response signal in stages according to the data flow until generation , optimization without a separate controller to each of the blocks sequentially , and the block to operate with a clock , the digital circuit structure of a passive RFID tag is provided for supplying a clock for each block . According to the present invention by the action of each block at different times of the passive RFID tag digital circuit , it is effective to reduce the overall power consumption is less hardware is required to operate .
