| Abstract: |
| The operational principle of POCSAG code protocol, FLEX code protocol and device based on waked - up function are introduced. Through calculating and analyzing three working models, the advantages, disadvantages and power consumption of these methods are compared with each other. Finally, according to the principle of passive RF - tag, a new ultralow consumption design scheme is presented which is applicable to battery of system power supply. |
