THE RESEARCH AND APPLICATION OF MICOR-POWER ACTIVE RFID BASED ON LF WAKE-UPTECHNOLOGY Cao Shihua1 Zhaofang2 (1.HangZhou Normal University, 2.Beijing University of Posts and Telecommunications ) Abstract: Tags of micro-power active RFID system are usually supllied by cells , the power consumption is a crucial factor. The currently applied operating mode is of timing wake-up. In this paper, presented the method of LF wake-up technology , discussed how to use it to solve the low-power problem of active RFID tag. Put forward the crucial electrocircuit and working program flow. Practices show that this solution is capable of solving the problem of low-power of active RFID.
